Image Quality Checking

Hai all,
I want to develope a java software that conducts a number of image quality tests. All these tests should be compatible with x9.37 standard.
That means I want to compare the pixel values against the value set by the x9.37 standard. But I don't know these values.
Can anyone help me for finding how to go about it? Please it is an urgent work. I want to do the following tests on images:
Too light,too dark, bars/streaks,out of focus,folded edges,skewed image,piggy backed images etc.
Regards,
Cochu.

Does this only happen with images loaded from the internet?
Does this also happen if you open a locally stored image that you know is good?
You can check the connection settings.

Image Quality Checking in Java

Hi All,
I want to develope a software in Java for conducting Image Quality testing. The idea I had in mind is to analyse the image pixel by pixel and doing the test. But then it is taking a lot of time to finish the test for a 200 by 200 DPI Tiff image.
Can you suggest any other idea to conduct quality tests on Tiff Image(such as Too dark/too light,streaks or bars,folded corners etc) in Java? I searched a lot in net and posted in many forums , but nothing come up.
Many third party softwares are there offering the solution which are very fast for the same image which I tested, taking only less than 1 sec for 2 images. So they have some other idea to test the image rather than going for pixel by pixel.

Cochu.

Image quality check

I need to check the quality of the image before sending it to the image processing software.
Basically I need to decide if the image needs to be preprocessed before giving it to OCR e.g. if the image is blur or rotated. I have a software which can make some corrections (i.e. image processing software) but it doesn't support analysis of image.
Is there an API which can help me analyze the quality of the image.

You can create a preset in preflight to look for images below your chosen resolution.

Low image quality check?

I have a lengthy catalog layout. Can InDesign be told to do some kind of a check to tell me if any of my art is low res without me having to go through and check each piece?

You can create a preset in preflight to look for images below your chosen resolution.

NOT happy with image quality of Lightroom 1.1

Sure, LR now launches faster and the interface looks a bit nicer. And the more capable sharpening controls and the clarity slider which mimics contrast enhancement with USM are nice additions, but has anyone else notice what happened to the image quality?
First, while formerly LR and ACR struck a great balance between detail and noise suppressionerring on the side of maintaining detail even at the expense of slightly higher noise levelsit appears the goal for the redesign has been to minimize the appearance of noise at all costs. It just so happens that yesterday afternoon, I'd shot some available light candids (up to ISO 800) of the staff at a local health care facility and was intent on using them as a trial run on Lightroom 1.1. Well, the difference in image quality jumped right out at me: there was no granular noise at all remaining, even in the ISO 800 shots, but neither was there any fine detail. I use a Canon 5D, and while I'm accustomed to slightly higher levels of chroma noise, images up to ISO 1600 in even the worse lighting are always full of fine detail. Fine structures like strands of hair and eye lashes have now lost their delicacy, and have instead become coarse, unnaturally painterly analogs. Looking into shadow areas, I can see the results of what seems to be luminance noise smearing at work, obliterating noise and detail along with it. I never used Raw Shooter because I'm a Mac user (2x2GHz G5 w/2GB RAM and 250GB HD), but if this is the result of incorporating Pixmantic's technology, the result is not a positive one from my standpoint. The images I shot yesterday are to be cropped to 4:5 proportions, then printed 20" x 25", at which size the processing artifacts and lack of fine detail in these LR1.1 conversions becomes even more apparent. I've even tried turning off all image processing options: Clarity, Sharpening and NR (neither of which I ever use in RAW conversion, anyway)... It simply seems this noise smearing is part of the baseline RAW processing, and it really, really bites. Am I missing something? Is there some way to actually turn off this processing that looks uncomfortably like the "watercolor" noise reduction that Kodak and Panasonic use for their compact digicams. Yuck!
Secondly, is there a way to get back the suppression of hot and stuck pixels that LR used to perform? Now, my high ISO files are riddled with them, the same as they would be when converted with Aperture or Canon's DPP. Default suppression of hot and stuck pixels was a major advantage of LR/ACR, and contributed in no small bit to my adoption of LR as my standard tool for RAW conversion due to the amount of high ISO, low light photography I do. What's even worse, is that the random-color speckles are now smudged into the image along with all the other noise data that's being smoothed out, resulting in images that looks more like impressionist paintings than photographs.
I thought about reinstalling LR1.0 and just continuing to use that, but if LR1.1 is an indication of the direction Adobe is going to take in the development of the software, I really don't see the point of continuing to use the softwareparticularly when I had a few existing problems with LR1.0 that were never resolved, such as crashing during the import of photos from a memory card and progressively slower preview rendering as the size of my library increased. So, I'm probably going to go back to using Aperture, which is itself not free of IQ foibles, but certainly looks much more attractive now in comparison to LR1.1.
Anybody notice the same things with IQ? Anybody got any suggestions of how to get more natural-looking conversions before I remove LR and go back to Aperture?

Jeff,
I mean no disrespect. But I would like to see samples of 1.1 compared to 1.0 of the same image (ISO 400, and/or 800), because I do not want to convert my library to a catalog until I know whether or not I like the image quality. Why is it so hard to get one good sample. That is all I am asking. I would just rather not jump through hoops to go back to 1.0 if I do not like 1.1....That is all
And yes, after well over 400 printed articles I can tell what an image will look like in print when I view it 1:1.... I can tell if the eyelashes or pores on someones face, the detail in a rug, or wood grain will be detailed on the off set printed page if I look at the image at 1:1 and see smudging...this means to me that the most detail possible is NOT going to translate to the page. If however I CAN see detail in those types of areas, clearly (ie no smudging), than I know that I will see those fine details on the page. If these fine details were not important than we would all still be shooting with 3 and 4 mp cameras. Those fine details that are only visible to our eyes at a 1:1 preview on screen, are important on the printed page.
Oh, and I am not chest thumping. You can check my history here, I do not have a history of that type of activity. I am simply asking to see samples before I update....
I am very discriminating Pro, not some over testing, too much time on my hands, complaining , over paid amateur who only has time to complain that their test chart is out of focus. Or that they can measure toooo much noise at ISO what ever, instead of actually making photos. I actually make my living taking photos. And my clients have come to expect a certain level of quality from me. They comment all the time how much higher quality my images are than some of the other photogs they use. And I am still shooting a D60, where as these others are shooting 5d's and D2X's.
Jeff, I am not against you or Adobe. Matter of fact, I LOVE LR. It has changed my work flow in a very positive direction. I think it is wonderful. I just want one sample.... I am asking nicely: Please with sugar on top :)
If you can't give me a sample, than please at least reassure me that it will be easy to go back to 1.0 for the time being. Is it as easy as uninstalling 1.1, reinstalling 1.0 and recovering my DB from a current backup? If so, than fine, I will go this route........... If not, than I am hoping for a sample.
Thank you very kindly Jeff for engaging in this lively conversation. I do appreciate your comments and participation on this forum. And please note that none of this is said with attitude or malice. I know that some times a writers intent or emotional state is easy to misinterpret in a forum like this. So please know that I am calm and not angry, just curious about image quality.
Ok. I will shut up now. Thanks again

Satellite S70-A-11H web camera image quality is not good

Hi,
Running windows 8.1 which came with the laptop.
New out of the box.
As per title.
I find the image quality of the camera image to be very grainy, poor color etc.
When I start the web camera using the search bar on the right, it starts using the Microsoft application, when you scroll down to settings all that is available under settings/options is Photo aspect ratio, Grid lines, Location info.
I have been in touch with Toshiba Tech support who advised to do a Laptop refresh, which I did.
This made no difference.
After which they asked me to find the Toshiba web camera application on the laptop, this should have been in the Program Files folder in the Toshiba folder.
This application does not exist on my laptop.
The tech checked the same model laptop that he had available, which I was told when he selected the web camera, it opened using the Toshiba Web camera application, not Microsoft.
I have looked at other Toshiba laptops with web cameras, and found the image quality to be better. Unable to get to settings as these laptops were on display and in demo mode, hence locked down to some extent.
I can't believe that a web camera in this day and age for this value of laptop to have such poor image quality. My digital camera from 10year ago has better image quality.
I have checked through the laptop, and I do not have this application installed.
I have checked for updated drivers and software for my laptop, and cannot find this application to be applicable for my laptop. Drivers etc appear to be up to date.
I would like to know, do other users of this S series have any issue of camera image quality.
When the camera is selected what application is being used, Toshiba or Microsoft.
Is Toshiba web camera application applicable to Windows 8.1, as I cannot see it listed for 8.1
Does this sound like a hardware fault or a application/software issue.
Any direction or help on this matter would be appreciated, as I am getting to the point of returning this laptop for a refund.
Thanks in advance.
D.
Yes, I have tried using the FORCE!

> The tech checked the same model laptop that he had available, which I was told when he selected the web camera, it opened using the Toshiba Web camera application, not Microsoft.
The Toshiba webcam application is available for Win 7 system but the Win 8 and Windows 8.1 system use the own Microsoft webcam application.
> I have looked at other Toshiba laptops with web cameras, and found the image quality to be better.
Different Toshiba notebooks are equipped with different webcams.
Satellite S70-A-11H was equipped with a *0.92 mega pixel webcam*
A Satellite A660 for example was equipped with an _1.3M mega pixel webcam_
So there is a difference in webcam resolution

Image quality problem when Printing Booklet to PDF

Hi!
I've searched the entire web trying to find a working solution for my problem but I wasn't able to find anything...
I've created a A5 vertical page document in InDesign CS6, filled with High-Quality photographs. I now want to print it as a booklet (to a PDF file) so I can save it and print it in a professional establishment.
The problem is, when I do this, the image quality turns out terrible...
I've checked my Print Settings and I can't find anything wrong...
Setup - A4 horizontally, and Graphics - Images - Send Data - is set to All.
Is there anything else I can do/try? What can I be doing wrong?
Here is an image of my print settings:
When I export the document normally to PDF the image quality is fine, but it doesn't have the booklet layout which I need, it just exports single A5 pages one after the other. If I try to print this pdf as a booklet in Adobe Reader the same thing happens to the images, they loose quality.
Please help!!
Thanks : )

Hi! Thank you for your quick and helpful answer.
There's definetly something wrong with the PDF printer properties... It was on standard default, as you said... but it still didn't work when I changed it to press quality (also tried high-quality print), changed the dpi's and other few settings on the advanced preferences
My solution was to download a free-trial of a professional pdf editor/creator (Soda PDF) and print it to that program... but, of course, this is not a long-term solution...
I'll try and see if I can find any help in changing the settings to get the best quality in printing of the adobe acrobat program.
Thanks!
p.s: I think I meant to say "graphic press" when I wrote professional establishment, I'm not sure how you say it in English.

Is iWeb 08's image quality horrible?...

Has Apple resolved the image quality problems we are having?
Does anyone have a workaround for the poor image quality we're getting in iWeb - one that doesn't involve converting images to swf and embedding as a web snippet.
If others are experiencing the same problems with image quality please speak up and voice your experiences.

!! Exporting SWF file in PDF reduces image quality.

Hello,
I have a file with many multi-state picture frames and buttons for them. I export it in pieces in SWF format, then I put the SWF's back in the document as a new layer and export as interactive PDF. Finally everything worked fine, except that PDF opens in a larger then normal zoom and when zooming in on pictures the quality is very poor I am guessing 72ppi at the intended zoom. I check the SWF file and see that its image quality is good when zoomed, so the problem is with the way the PDF has exported the SWF.
notes: I made sure the settings were to export at 300ppi and high image quality. When I take a single multi-state frame with its associated button and export to SWF then PDF the image quality is maintained.... however I have over 150 image frames, so I rather not export them individually. Please, please reply... any suggestions will be gratefully excepted.

edit your image in photoshop and experiment with various settings/size. there's no magic high quality small file size setting.
it's a trade-off. the higher the quality and the greater the image dimensions, the greater the file size. you have to decide where those are acceptable.

Poor image quality when sending via Mail?

This is a new problem for me, yet I'm doing the same thing I always have... Previously, I could "Email" from iPhoto, select an image quality and size, and have it appear correctly as an attachment in a new message, with appropriate quality, with a subject to the effect of "1 Great iPhoto".
Now, however, regardless of the quality/size level I select, I get a small, pixellated, poor quality image attached with a non-sensical subject like cscp_W149.
Any idea what's going on?
Thanks

you are doing it wrong and selecting the thumbnail
THere are many correct ways to email photos with iPhoto - none of them involve going into the iPhoto library and mucking around (which can corrupt your library and cause you to lose data)
The easiest way is to select the photo(s) in iPhoto and click on the mail icon in the toolbar - if it is not there go to the view window and under the shoe in toolbar command check mail

Image Quality In Crystal Reports for Visual Studio 2010

I am using the new production release of Crystal Reports for Visual Studio 2010 and I am having an issue with image quality when adding an image to a crystal report.
The image itself is a .TIF file, and when opened in Windows, the quality of the image, which is mostly text, is very high. The image was created from a electronic PDF form and I intend to use this as a background for the crystal report, over which I will place data fields.
As soon as the image is added to the report you can see the degradation in quality in the design window and in the preview window within visual studio. The quality remains low when viewing the report in the WPF report viewer and when printing from this control.
I have ensured the "Retain Original Image Color Depth" option is checked but this has made no difference (the image is black and white anyway).
The image in the report has been left at its native size, no resizing at all. The image is 355KB in size if that's relevant.
Is there a reason the image looses quality when added to a report? Is it being compressed? More importantly, is there a way to make the image retain its native quality when adding it to a crystal report?
Thanks in advance.

The following image is the image I am trying to display. Although imageshack has converted it to a png, if you right click and save the image you can open it and zoom in with little image degradation.
http://img132.imageshack.us/i/j301.png
The following is a screen shot of how the tif file looks in the designer when zooming in:
http://img138.imageshack.us/i/j30lowquantity.jpg
The second image has lost its clarity and is unusable when printing.
I hope this helps.

Poor image quality save for web

It doesn't matter whether i'm exporting from Ai or Ps or whether it's CS6 or CC. I have changed the raster settings in Ai and i've also tried all optimization options with all different export file types (jpg, png, gif) at all different quality settings. It doesn't matter if I start with an ai, eps, pdf, png... the export result is always poor quality.
I have tried exporting at 300ppi and that does fix the quality issue and bloats the file size, but this way (the export route) is so time consuming since you have to resize your artwork each time as well as the artboard so that it doesn't cut off pixels. Save for web never used to have these quality issues and it also never used to cut off pixels around the edges. These workarounds prove very time consuming and produce file sizes that are not ideal.
When i first noticed this issue I was using Mavericks with CS6 and since am using Yosemite and Creative Cloud.
Steps to reproduce:
1. Create any bitmap or vector graphic in Ai or Ps, It doesn't matter whether you convert text to outlines or not
2. Save for web
3. View image in any application or browser to see poor quality and pixel trimming. Others running the same version and system are not having this issue, but I have checked many forums and found many others that do have this same issue but can't seem to find a solution.
Results:stair stepping, degradation, pixel trimming, general poor image quality
Expected results: Previously the save for web feature allowed for a decent quality image

First try the Cleaner. here's the link for CC but there exists one for Cs6 as well Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
Everything I have read says that you kind of have to compromise file-size for quality. Could you post a screenshot of your settings?
also, if it helps: Creative Suite * Optimizing images

Very Poor Image Quality In Viewer, JPEG Artifacts

I upgraded to Aperture 3 some time ago, and purchased a new Mac Pro specifically for this application. I am an amature/ sometime professional photographer and I have been using Aperture since Version 1. This weekend I finally had some time to sit down with Aperture 3 for some serious work with my scanned film images. These are large TIF masters scanned in with my Nikon CoolScan 9000. Some are medium format black & white Tri-X Pan images, others are 35mm, also black & white Tri-X Pan. Everything scanned in on the Nikon is at the maximum resolution for the master, on the theory that I can always bump it down later if that's necessary.
I am noticing vastly lower image quality in the viewer then with Aperture 2. Specifically, I am seeing massive JPEG artifacts in the viewer image then I have ever seen before. The images also render darker in the viewer then before. These artifacts do not appear when I export my images (say as JPEGS for posting to a web page), or when I print them. The quality of the exported and print images seem just fine and the exported JPEGS are completely free of the artifacts I am seeing in the viewer.
I have tried rebuilding the previews several times, experimenting with different quality settings. I have experimented with different proof profile settings. My printer is an Epson Stylus Photo R1800 and I have tried various paper settings for it as well as other proof profile settings such as the Adobe and Apple RGB settings and the generic grey profiles. Every time I change a setting I have forced a rebuild of the previews to no detectable effect. Nothing I do seems to have any effect whatsoever on the image quality in the viewer which remains relentlessly the same as it always was.
This poor viewer image quality is making it very difficult to work in Aperture 3. I suspect there is a setting somewhere like an easter egg in this new Aperture I haven't found yet but it is becoming very frustraiting and I could use a pointer because, again, nothing I have tried has changed the image quality in the viewer in any way I can detect and the photos look perfectly awful there...darker and loaded with JPEG artifacts. Things export and print just fine, but I need to see what I am going to get in the viewer or I can't do my work.

I interpret this as ... Eventually you should be looking at the Master with the Version changes applied. I'm assuming at this point, you aren't looking at the Preview. Since you don't need Previews to view and edit your images.
Yeah...that's sort of what I gleaned from that text. I was experimenting with the preview settings because I couldn't see any other way to fix the problem. What I'm hearing now is that the problem has no fix. If you scan in black & white film negatives (or anything else that's monochrome I suppose) with the color space set as gray scale you are asking for trouble. The sense I get from the text Gomez Addams referred me to is the behavior in that case is unpredictable, and furthermore film photographers aren't the customer base Apple is trying to cultivate with this product.
Aperture is designed to work with images from digital cameras which use an RGB color space...
Okay...fine. I have several digital cameras I occasionally use for professional work and I am here to tell you Aperture is an absolute blessing for that work. I do shoots every now and then for a local community newspaper and I would not want to live without this product. I remember back when I was a teenager in the 70s being up all night in the darkroom to get an assignment I'd had to cover right before deadline, and then go to my day job the next morning without any sleep. This is much better. And even with the personal art photography it is good to be able to just scan things in and make adjustments in the computer. You can do so much more. I would not want to go back.
But I reckon I need to find something I can rely on for my film work, or at least my black & white film work because as I read this Apple is not supporting film photography with this product and black & white film photography in particular and some of us still use film. No...scanning in my Tri-X negatives in the CoolScan as color produces weird results and anyway Photoshop and GIMP for goodness sakes seem to handle grayscale files just fine. Plus, I've already got thousands of those negatives scanned, I am not rescanning all that in RGB just to satisfy Aperture. The color slide film scans don't seem to be a problem, but that's now. I think I'm being told not to count on That always being the case either.
Aperture is designed to work with images from digital cameras...
Okay...fine...film is old technology after all, Nikon isn't even making their film scanners anymore...check the prices on the few still new-in-the-box ones left out there. My CoolScan 9000 is selling for twice on the second-hand market what I paid for it new and new it wasn't cheap. And yet it's not economically viable for Nikon to continue making them. Film is dying. But I still like working with film and film cameras and I reckon I'll keep doing that until I can't get any more of it and my stash of Tri-X Pan bulk rolls runs out.
Thank you all very much for your help. I think I see what I need to do now.

I thought of that too so I tested on another machine with retina display and the file i saved on my machine looked bad on my machine and on the other comparable machine/display. So I sent them the original vector ai file and watched while they saved it the exact same way on their machine and the file looked fine on both of our machines/displays.
All of the settings they used appeared the same as what I used but with different results. I don't recall changing anything but does anyone know if there is some setting that could have been changed that is causing this issue?

Poor image quality in preview - CR2008Sp4

Hi,
I have a report, designed in CR 2008 SP4, with a logo image(blob field - bmp) on the top of the page.
When previewing the report from my Win Forms app, the image quality is poor/grainy.
If I export it to PDF (either from the previewer or from code) or print it, the image quality is perfect.
I have the report option 'Retain Original Image Color Depth' ticked.
Anyone have any ideas?
Thanks,
Fergus

Hi Bhushan,
Thanks for the reply.
Does the image come up fine when the report is viewed from the CR designer?
>> Yes
Is it a .bmp, jpeg or something else?
>> In the sample I'm providing, it's a jpg but I can confirm similar behaviour with bmps
How large is the image?
>> In this sample, 57kb
Is it on the main report or inside a subreport?
>> Main report
Could you provide the snapshots of the report from the designer and from the viewer?
>> Sure, see this [snapshot|http://img36.imageshack.us/img36/2263/qualityexample.jpg] and the original [logo|http://img849.imageshack.us/img849/2573/acmeltdheader.jpg]
Try checking 'No Printer' in the Page setup of CR designer and then add the report to the app.
See how it behaves.
>> Still loss of quality - no change
Thanks,
Fergus
