How to measure on depth image

I am trying to measure the area of an object that has been captured by a ToF camera.
The object is the round "sausage" like object. I am wondering how I should measure on the depth image?
I also have an RGB image and originally I considered to detect the object there, and then detect the coordinates for the ROI, and then go and read the values on the depth image.
However due to poor lighting conditions that is a little difficult.
I added the VI that loads and displays this image and the file for this image (the Depth_info vi is a sub vi).
Does anyone have a lead that could nodge me in the right direction?
Thanks.

Hello,
the simplest way would be to detect the object on the texture image and extract the corresponding depth values (if your texture and depth images are aligned/calibrated). But you've got the problem with lighting conditions. Can you improve this to illuminate the object more? Can the countours of the object be extracted on the illuminated texture image?
On the other hand, you could perform some sort of segmentation on the depth image to separate the measured object from the background and then calculate the area. Can you attach the X,Y,Z information of your scene?
Best regards,

HT1198 I shared disk space and my iPhoto library as described in this article. When creating the disk image, I thought I had set aside enough space to allow for growth (50G). I'm running out of space. What's the best way to increase the disk image size?

Done. Thank you, Allan.
The sparse image article you sent a link to needs a little updating (or there's some variability in prompts (no password was required) with my OS and/or Disk Utility version), but it worked.
Phew! It would have been much more time consuming to use Time Machine to recover all my photos after repartitioning the drive.

Does duplicating layers from an 8-bit PSD reduce the color depth of a new 16-bit edit?

I have been using several versions of Photoshop over the years starting with CS3, then CS6, and finally CC. Through 2012, all my RAW files were converted using 16-bit color depth in ACR. However, in examining my files recently, I noticed all were in 8-bit color-depth, which likely happened once I upgraded to CS6 and ACR left 8-bit as the default. As such, I now have hundreds of images that I wanted to edit in 16-bits that have been converted to 8-bit starting with my ACR export. The files are all RAWs from cameras like the Canon 5D, 5D Mark III, Olympus OMD EM5, and Sony RX100.
I have 8-bit PSDs of my edits of these files which contains multiple layers. I use features from the Nik and Topaz collections for noise reduction, contrast enhancement, black and white conversion, and sharpening. I also use layered Photoshop features like Selective Color. I want to know if I can simply duplicate the layers from the 8-bit PSD files onto a new 16-bit RAW converted background layer rather than re-edit each and every file. There would be no change in the crop of other reasons why the layers would not match up, but I am concerned that duplicating those layers might throw away the benefit of moving to 16-bit since they were created in an 8-bit color-depth.
As a test, I looked at a few files where I had pushed the shadows and colors to an extent and duplicated the layers from an 8-bit conversion to a 16-bit conversion and could see no difference. I am not sure if this is because Photoshop has become very good at reducing color-depth without a perceptible difference or if I am throwing away information in moving the layers.
I work off of a fairly modern computer and a top-end Eizo CG276 self-calibrating monitor and good video card. I am extremely sensitive to color and shade changes as well.
Thanks for any help, I am a bit stressed at the thought of re-editing hundreds of files from step 1, but it is important to me that I not throw away color information and it is better I start re-editing now rather than years from now.

While raw file contain a 8Bit jpeg previews image in some color space. The RAW sensor data is not a color image and has no color space and the bit dept of pixels depend on the manufacturing. Most sensor produce one value for each pixel 10 to 14 bit seems to be common. Sensors only measure the light intensity not color. If front of each pixel sensor is a color filter which lets Red or Green or Blue light be measured for intensity.
A RAW converter can convert your sensors RAW data into a color RGB image in any color work-space in 8 or 16 bit color depth. No Adobe update went around and scanning your computer looking for 16bit color depth images and convert all of them to 8bit color. Your ACR workflow settings may have been change from 16 bit color to 8 bit color by you or set to 8bit by some update or script used. So you current ACR work-flow setting may be converint tou raw datya into 8bit RGB images. As long as you have you raw files you can reprocess these to produce 16Bit color RGB Image by makinf the proper ACR work-flow settings. You can also change your 8bit image to 16 bit image mode. However this will not recover any color quality lost or posterization that has set in.. It will give you a bit more latitude using Photoshop filters which may help you not get banding posterization.

SP 2010 Publishing - Rollup and Page Images not visible when entering page edit mode

All:
Hello, I have an odd issue recently appearing after installation of FEB 2013 CU install. When users select to Edit a Publishing Page the Rollup Image and also Page Image(Article Page Layout) are not visible. Only the "Click here to insert Image from
SharePoint" link is visible.
The issue has be confirmed in 5 servers across two farms
DEV, QA, and PROD on client recently updated
DEV and PROD in a completely separate client farm
I have confirmed the issue does not exist in two separate farms running April 2012 CU. In both of those environments the image appears with issue even in Edit page mode.
In the farms where the issue exists you can click the insert image link and simply hit OK to see the image again. An easy enough work around for tech savvy but my client's content admins are very confused/frustrated by.
Is this a bug? I have confirmed in two separate farms including brand new web applications using out of the box publishing site templates.

Hi.
We have been facing the same issue in a 2013-environment (SP1), but in this case an upgraded 2010 Solution, which still runs in 2010-mode. Because of this, SharePoint still use resource-files in the 14-hive (as we have not performed an upgrade of Master
Pages etc.) The problem is also reproduced on a clean 2010 Site Collection in the same 2013-environment.
I have managed to find the cause of the problem (at least in our environment), and that is that as long as the selected picture/image has
not defined an "AltText"/"Alternate Text" the problem seems to occur.
In other words, try to define an Alternate Text and click OK in the "Edit Image Properties" Dialog.
I don't know if this may be the case for everyone else, but give it a try.
From this, I've further discovered (after hours of js-debugging) that there is a minor change (from 2010 to 2013) in a js-file called "SelectorControls.js" which is responsible for updating the various controls used in Page Layouts etc.
The problem exist in a method called ASO_UpdateButtonsAndPanels(), which checks whether the Image Control in question has content or not (Url). The local variable "hasContent" is then determined of an if statement, if(this.AssetData.ManageLinkDisplayText)
which in 2010 (14-hive) seems to be "true" regardless whether the Control is of type Image or Hyperlink. Further the code checks for AssetText (Alternate Text) which on an Image may be left empty.
In 2013 (15-hive) however, this if statement has been changed to, if(this.SelectorType==ConstLinkSelectorType), which clearly states "Image" or "Link" depending on the type of control.
I don't know if this is the cause of the problem in 2013, but in 2010 it seems to be exactly that.
Pending a solution from Microsoft, we have modified SelectorControls.js to overcome this issue until the customer decides to do a Visual Upgrade to 2013.
This is by all means not a supported nor a a permanent solution to the problem, as future Hotfixes, Service Pack etc. may "reset" our fix.
Below is a copy of the working solution:
function ASO_UpdateButtonsAndPanels()
{ULSuBa:;
var hasContent=!!this.AssetData.AssetUrl;
//SharePoint 2010: ManageLinkDisplayText is always "True"
//var hasContent=!!this.AssetData.AssetUrl;
//if(this.AssetData.ManageLinkDisplayText)
//hasContent=hasContent && !!this.AssetData.AssetText;
//SharePoint 2013
//var a=!!this.AssetData.AssetUrl;
//if(this.SelectorType==ConstLinkSelectorType) a = a && !!this.AssetData.AssetText;
//Fix for preventing existing selected image to disappear when saving page and/or editing a page with existing image.
if(this.SelectorType!=ConstImageSelectorType)
if(this.AssetData.ManageLinkDisplayText)
hasContent=hasContent && !!this.AssetData.AssetText;
if( hasContent )
if (this.ClearAssetButton !=null)
this.ClearAssetButton.EnableButton();
this.GetAssetSelectedPanel().style.display="inline";
this.GetEmptyPanel().style.display="none";
else
if (this.ClearAssetButton !=null)
this.ClearAssetButton.DisableButton();
this.GetAssetSelectedPanel().style.display="none";
this.GetEmptyPanel().style.display="inline";
I hope this helps anyone else struggling with the same problem.
Thanks!

Importing 32 bits images

Hello! I'm trying to import a 32bits depth image format using the FBIO sample.
I set the depth to 32 with the following instruction
ERR(suites.IOInSuite1()->AEGP_SetInSpecDepth(specH, 32));
And the project tab shows me that the image has million of colors instead 256, but when I try to fill out the effect world in the DrawSparseFrame function, the world that AE sends me (PF_EffectWorld *wP) has 8 bits depth.
How can I receive a correct effectworld? I've tryed to create a new 32 bits world and assign it
suites.WorldSuite3()->AEGP_FillOutPFEffectWorld( my32World, wP );
to the wP effect world, but it doesn't work (in fact, creating a new 8 bits world and assigning it to the in-out wP world neither works...)
Any advice?
Thanks!

OK, when I set the project adjustments to 32 bpc depth, I get a wP->data with a float size (I test the wP->rowSize to check it). The problem now is when I set the project adjustments to 16 bpc... the wP->data that I receive has 8 bits size, and AE shows the colors wrong... it is a bug?
When I set the depth of the image imported to
ERR(suites.IOInSuite1()->AEGP_SetInSpecDepth(specH, 32)); // 4 channels , 8 bpc
the image is showed correctly in 8 and 16 bpc, but wrong in 32 bpc.
If I set ...
ERR(suites.IOInSuite1()->AEGP_SetInSpecDepth(specH, 64)); //4 channels, 16 bpc
the image is showed correctly in 8 and 16 bpc, but wrong in 32 bpc.
If I set
ERR(suites.IOInSuite1()->AEGP_SetInSpecDepth(specH, 128)); // 4 channels, 32 bpc
the image is showed correctly in 8 and 32 bpc, but wrong in 16 bpc.
Maybe a gamma correction issue?

Find defects in a 3D image

Hello,
i'm working on a machine that uses a laser scanner to measure gears.
I acquire a XYZ points cloud for each tooth of the gear and i compare them with a "reference" point cloud that is my template, the result of this comparison is an image that represent the Z difference between source and template points cloud. The difference image has a dynamic of 0.3mm in Z using 256 gray levels, 128 grey if the difference is 0, values < 128 are "defects\hole" values > 128 are "defets\peack".
Now i have to develop the final part of the algorithm that discriminates real defects against noise (coming from measure error of gear itself).
I tried using threshold methods but doesn't work in a reliable way.
Attached a couple difference images that have defects
Thanks for any suggestion

Hello Alessandro,
by seeding the values I meant that the segmentation procedure (GrabCut for example) needs an input labeled mask.
The options are:
1. Obvious background
2. Obvious foreground
3. Possible background
4. Possible foreground
For more information, you can check the OpenCV's GrabCut arguments explanation here:
http://docs.opencv.org/modules/imgproc/doc/miscellaneous_transformations.html#grabcut
You basically need to provide some information of the underlying pixels before running the algorithm. Same goes for example with GrowCut segmentation. I know there is a GrowCut segmentation algorithm written in Matlab, but not sure for OpenCV.
Here is a working .dll implementation of OpenCV's GrabCut algorithm in Labview:
https://decibel.ni.com/content/blogs/kl3m3n/2013/07/30/color-histogram-matching-and-grabcut-segmenta...
It uses a ROI rectangle, where all pixels outside the rectangle are considered as a positive background pixels.
Regarding the difference in the depth direction, you would need to display the 3D pointcloud after the ICP alignment and extract the Zbuffer value from both pointclouds using the same viewpoint. You would basically just need to snap the depth image from the active viewpoint. PCL (point cloud library) has this option I think. This should be much faster than your approach.
See: http://pointclouds.org/documentation/tutorials/range_image_creation.php
This should work after aligning both pointclouds and using a proper sensor position. First, get the depth image of one pointcloud and then the other using the same parameters of the sensor orientation. Then you just calculate the difference.
I have not tried this, but I think it should work. If you are interested, I can try to (when I get the chance) build a .dll which can be called in Labview? That is if you don't beat me to it!
Hope this helps a bit.
Best regards,
K

Binary conversion of a big image leads to "java.lang.OutOfMemoryError"?

Hi,
My program loads a black and white 1 bit depth image of around 20 - 30mb. When I try to convert it to binary image, it gives the following error: java.lang.OutOfMemoryError: Java heap spaceI am converting a bufferedimage to binaryimage. I used the following conversion method:
// This method converts an image to a binary image:
     public static BufferedImage convert (BufferedImage src, int type)
          int w = src.getWidth ();
          int h = src.getHeight ();
          BufferedImage dst = new BufferedImage (w, h, type);
        Graphics2D g = dst.createGraphics ();
        g.drawRenderedImage (src, null);
        g.dispose ();
          return dst;
     }The program was working well before but now it keeps giving the heap memory error which is really weird. Is there any way I can fix this? Can anybody suggest a better way to convert a black and white image to binary data. Thanks.

You could increase maximum memory (-Xmx): [http://java.sun.com/javase/6/docs/technotes/tools/windows/java.html]

Using the back button causes infinite loop between articles

Hi i have a folio that has a series of projects, and i wanted to use the back option as various access points to each project
goto://FolioNavigation/lastview
but each project has an image article associated with it, and this has a button on it back specifically to the project main article. But when u click the back button now on that main artcile, it takes u to the image article, not back to where the person wud have wanted to be.
I cannot think of a work around other than going back to using specific page navto but that means determining the access point which is not possible. Or duplicated the articles entirely.
Any help appreciated.
Rob

found solution. you have to use the goto://FolioNavigation/lastview
in the back option on the image page as wel. then it knows not to cause infinite loop

Linked images: BitsPerPixel?

Hello,
My style of work is to place raster 16 bit images in Illustrator and work with typography over them. After I'm done I just export the artwork directly from Illustrator for printing. Now I'm starting to get very concerned about the output quality of my linked images since all exported files from Illustrator (regardless of file type) have 8 bits per pixel. I have 2 questions about this:
1. Should I continue to export files from illustrator as final files for printing? Or should I place the vector part (done in Illustrator) to Photoshop and save it for printing there? Or is there something else I should know about this BitPerPixel conversion?
2. Whenever I place a vector image (8 bit and 16 bit) to illustrator, it shows 24 bit in document info -> linked images. Why is this happening?
Thank you very much,
Savo Bursac

You're worrying about nothing. No method I know of can actually print 16bit - even the finest inkjet printers with all their nano drops and dithering tricks can't. However, that in itself contains the answer. Ultimately it doesn't matter what bit-depth, for printing it only matters how the color is perceptively transformed, meaning
a) how fine/ dense the raster is
b) how pigmented/ saturated/ opaque each ink area or halftone spot is
c) the reflective and transmissive properties of the printing substrate are figured in
That's what color profiles do and what they are meant for. They may use 16bit or even float values to improve mathematical precision, but ultimately most of the time a single ink channel won't even exhaust the number of levels that could be expressed with 8bit. Since e.g. offset inks have a specific viscosity that prevents them from printing dots smaller than a specific size or below a certain opacity, the printing plate and thus the color profile used to create it would have to obey these physical limitations, limiting the range of possible variations. So in the end, all that matters is having a correct color profile and workflow built around it to be able to control how a high bit-depth image is transformed to a low range color space. Of course there may be potential to improve your output by doing part of this in Photoshop, but it will really depend on teh specifics...
it shows 24 bit in document inf
3 channels * 8bit per channel = 24bit

Default Image Rendition or resize image automatically

We use the column Rollup Image and have the blob cache enabled to use image rendition.
Is it possible to use this publishing image column with a default rendition (not full size) so the user has not to choose the rendition (or cannot choose it)?
Or what would be the best practise to get automatically resized Images? By publishing Image column or better by JavaScript?

Hi,
According to your description, my understanding is that you want to you want to know about how to use PublishingRollupImage Column to display a default image rendition and how to get automatically resized images.
Firstly, I suggest you can use the automatically resized in the rollup publishing image column. As the image renditions will choose for different device such as mobile phone, if they display as a default rendition, then it can't be enlarge if user want to
see more clearly.
About how to get automatically resized images, you can get image with RenditionID using Jquery.
Here is a code snippert for your reference:
<script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.7.1.min.js" />
<script type="text/javascript">
$(document).ready(function() {
$image = $(".article-content").find("img");
$image.each(function (i) {
var imagesrc = $(this).attr("src") + "?RenditionID=5";
$(this).attr("src",imagesrc);
</script>

Acquiring images from an Analog Camera using Arduino and LabVIEW

Hi All,
I posted this on the LabVIEW Arduino community but I am not sure it went through.
Check out this project I have been working on for the last two weeks.
It allows you to capture lowres/low bit depth images with arduino with LabVIEW (needs NI vision).
Here is the link
Feel free to use the code (it is all downloadable).

Hello cagell
I just wanted to exprees my thanks for sharing your awesome project with our community. I am a huge analog video enthusiast myself. All the best!

Creating Thumbnails of Images without AWT

I've searched in a lot of places, and am becoming increasingly surprised I cannot find a straightforward answer to a problem I have. I run Tomcat on a server which has no X11, and I do not want to install it. However, I am also trying to create a servlet which will take an image from a byte array and create a thumbnail of it.
While I have seen many examples of this, all use AWT, which seems to require using X11 or some windowing system even to run at all (despite my not trying to create a window or anything). While I understand that there is an option that can be added to the initialization script for Tomcat ("JAVA_OPTS=-Djava.awt.headless=true") I would far prefer simple code that didn't use AWT at all.
Does anyone know how to create a thumbnail or resize an image without the use of the AWT library whatsoever? Thanks very much!

Hmm... sorry I didn't know that.
I remember seeing some section on this website about Java Imaging or something like that and it seemed totally independent of AWT.
I came accross another imaging article:
http://johnbokma.com/java/obtaining-image-metadata.html , this one doesn't seem to use AWT - at least I don't see any in the imports.
May be Images are supposed to work only with AWT.
Here's another set of examples:
http://www.exampledepot.com/egs/javax.imageio/pkg.html
that demonstrates the javax.imageio package, but those examples also use AWT.
I think one could re-size an image on a website to create thumbnails, by specifying a percent width and height. and may be there's no need to have a package to create thumbnails on a web page when it could be done with HTML and that's probably why there isn't image processing for web pages (this is just my guess work, I could be wrong)

When Foreign Keys will conflict with FILLFACTOR

Samuel Lester: "Outstanding explanation, format, and write-up! Superb again Uwe!"
DB: "Very interesting both in content and technique. "

SQL Server: Create Random String Using CLR

C# code is used in SQL Server at all"

Samuel Lester: "Very good article and a great in-depth break-out that compliments your broader random string tech-net Wiki article. Great read!"
DRC: "It would have been better if the code would also provide the below details: 1. How to load the dll generated in SQL Server memory 2. Sample T SQL script to use the function and a sample output for the same. "
