Color Pattern Calibration

Does FIOS or a channel on FIOS provide a color pattern to calibrate the video on one's TV and Projector?  Thanks.

No. You'll have to use calibration discs such as Disney WOW, DVE, Spears and Munsil, etc.

  • Color pattern match in consumer producer architecture

    The way I currently have my code is as follows:
    If the number of matches in a color pattern match is greater than 0, it sends the information to the consumer loop.
    If it is not greater than 0, it doesn't send anything.
    What I was wondering is, if it finds a match the first time and it sends the information to the consumer loop, will the number of matches in the color pattern match return to 0 or will it be greater than 0 after the first match? If the number of matches in the color pattern match will be greater than 0 after the first match, and it will still be greater than 0, even though it doesn't find a match in the following scenarios, how can I make the number of matches in the color pattern match return to 0?

    it's hard to say unless you can post your code....have you tried probing tool,retain wire value,highlight execution,single stepping into and out, breakpoints?

  • Color pattern matching is very slow

    Hi
    I tried this code creating one vi application.
    After the testing with USB webcam I have realized that the color pattern matching is very slow. How to increase the speed and to work smoothly in real time.
    Thank you

    Hello tiho,
    the color pattern matching is not as fast as 8-bit matching, but should still be fast.
    For example, I am attaching a VI for color pattern matching where you load the image, create the template and search do the matching.
    In my example I tried color pattern matching on color image of size 4288x2848 pixels and the matching is performed in ~140 ms (~7Hz). So, for a smaller image, I think the real-time processing is quite achievable (I consider real-time 20 Hz or more). The only problem is the template learning, which in my case takes around 10 seconds. But you should learn the template only once in the initialization stage.

  • Color Pattern?

    In Diagnostic mode, I can see under LCD an option to change the color pattern, but I can't seem to. How do I do this?

    There is no way to change the color pattern. What you are seeing is simply a line of code from Apple. Perhaps they were testing a few different color patterns during development.

  • Error -1074395395 occurred at IMAQ Match Color Pattern after merge programs

    Dear all
    I  have 2 separate programs that use same source image (red01a1.jpg). The first find location of color particles (color location 01.vi) and second find location of particles after threshold  color image (particle location 01.vi).  Both of them run good.  
    But when  2 programs were merged  into one program (color sorter 01i.vi), that happened error . The error message is “Error -1074395395 occurred at IMAQ Match Color Pattern”. How can I fix it ?

  • Slowness of color pattern matching vi

    Hi,
    We're trying to implement a SLAM (simultaneous localization and mapping) algorithm in Labview based on kinect. In order to do so, the mapping robot should spot landmarks in real-time from the kinect image. We found the color pattern matching VI which does exactly what we need but the problem is that it's very slow (about 1.5 seconds for each image and total of 3 images each iteration). Is this the normal time for detecting landmarks in a kinect image? The robot can't map accurately when the iteration is so slow.
    Thanks,

  • IMAQ Learn Color Pattern hangs

    Running Labview 2012 SP1 and Vision Development Module 12.1.0.  IMAQ Learn Color Pattern appears to hang if you call it without defining an ROI.  See attached program - it is intended that user define an ROI then click "Define ROI" button.  If you click the button without first defining an ROI, Learn Color Pattern hangs for over a minute then returns OK.  I found a workaround for this by checking for a valid ROI before calling the VI, but it seems unusual behavior for Labview.

    Hi Bucky,
    I took a look at your program, and if I run it with highlight execution, I can see that the program is waiting on the Learn Color Pattern function as you said. However, I don't think this would be considered hanging. The front panel is still responsive, and if you add other processes to the program, they continue running while the Learn Color Pattern function is executing.
    I believe the long execution time is because when no ROI is specified, the function acts on the entire image, which takes a fair amount of time. You can confirm this by selecting a ROI that is almost the size of the entire image. The program takes a similarly long time to execute. The best way to cut down on execution time would be to select a smaller ROI. I hope this helps!

  • Weird colored patterns in RGB mode document with Illustrator CC

    Hi guys,
    I'm having weird glitches in Illustrator CC: when I open a new document with RGB mode, the artboard displays colored patterns :
    These patterns change when I move inside the artboard, when I zoom in ...
    I don't have this behavior when I work with a CMYK.
    It seems to be a graphic card issue but I don't have problem with other software (Photoshop, InDesign, Premiere ...) and my computer is brand new.
    I have a Lenovo ThinkPad W540 (http://shop.lenovo.com/us/en/laptops/thinkpad/w-series/w540/ with Windows 7 64 bits.
    Thank you !

    What are the Photoshop > Preferences > Transparency & Gamut > Transparency Settings?
    Boilerplate-text:
    Does turning off OpenGL in the Performance Preferences and restarting Photoshop have any bearing on the issue?
    Other than that are Photoshop and OS fully updated and have you performed the usual trouble-shooting routines (trashing prefs by keeping command-alt-shift/ctrl-alt-shift pressed while starting Photoshop, 3rd party plug-ins deactivation, system maintenance, font validation, etc.)?

  • Problem while using color pattern matching

    Currently we are doing projects on real time object tracking where we found one doubt that irrespective of the object size whether this color pattern match works or not . My questions are as follows:
    1. Whether it is applicable for objects moving far . Because as it moves far, the size of the object decreases such that the color pattern matching is not working what will be solution since we must use color image
    2. What is the difference in using scale and  rotate invarient in color pattern matching
    3. How we can effectively decrease the ROI depending upon the object position as per below attached screen shots .
    we have removed boundary box values of X and Y coordinates at the four corner but we can't track as the object moves far away or we can't decrease the ROI as the object moves far.
    4. whether it is possible to see the value of particular pixel  in LABVIEW vision development module as we seen only the coordinate position . whether it is applicable to see particular pixel value. Guide us
    please, see the below screen shots and provide the solution how effectively decrease or increase  the ROI depending on objects position using color pattern match

    problem in matching while object moves far.png ‏515 KB

    Hello,
    I have not been using the color pattern matching a lot (especially not in real-time). But since the pattern matching considers only small scale changes, you could try updating the color template every n-th iteration (depending on your setup and requirements). The major problem is the template size, since the color pattern matching tends to take quite a lot of time in learning the template. You would of course need to come up with some idea on how to change the subimage size, where the new template will be learned.
    This is the part of coarse (rough) object detection as was suggested by MoviJOHN. For example, if your object is distinctly red, you can extract the green channel from your rgb image and use threshold to roughly find the object and apply the new ROI - template.
    So:
    1. learn the template,
    2. use pattern matching with bounding rectangle (ROI) for the next couple of frames (you would need to experiment here where the detection fails -> how fast can you move the object away so that the detection fails),
    3. Before the detection fails -> rough object detection with some padded bounding rectangle (new ROI),
    4. Re-learn te template of new ROI and go back to 2.
    Again, the biggest issue is the template learning time - if you have a high resolution camera and the template is large, this won't satisfy your real-time application.
    You should set up the appropriate illumination first. The resolution is also important, since your object is moved back and forth (but the resolution will have a direct impact on the template learning time).

  • Color / Monitor Calibration on 10.4.11

    Hello !
    I have always used Adobe RGB to visually calibrate my HP ev19w monitor. The colors seemed to be OK and the whites were always very "clean" as I have only been working with monochrome images + have Adobe RGB as the workspace setting for Photoshop CS2.
    I have an Ati Mac edition 9600 graphics card and am running on OSX Tiger 10.4.11.
    I have now purchased a printer which was bundled with a HP Colorimeter (aka : Eye One Display 2) + I have downloaded + installed the latest driver. I have had several attempts using the device to calibrate my monitor - I cannot seem to get "clean whites" they seem to have an off-white / yellowish cast ? ....
    I am "totally clueless as to why" ? I cannot seem to get clean whites on my "calibrated monitor" !!!
    Any kind advice and expertise would be most appreciated ...
    Thank you in advance

    If I calibrate my monitor...
    You don't mention how you're doing that, and it makes a very big difference. If you mean the Calibrate function in the System Preferences, then it's a crap shoot. That function assumes your monitor is set to a 6500K white point and a 2.2 gamma, which is its starting point. That's the only way it has of even having a chance of guessing what you monitor looks like when you're done using Calibrate. And that's all it is, a guess. It can't account for how accurate your monitor presets are, the aging of the monitor colorants or drift. If color is critical, you must use a hardware/software solution to get a monitor profile that means anything.
    ...how do I then handle my digital photos when working w/ Photoshop.
    It's up to you. What Photoshop does is open and convert your images (if necessary) to the working color space. It passes that information off to ColorSync, which then translates it to your monitor profile. So no matter what the working space is, the color you end up viewing is your monitor's color space. Here's where you have to decide what to do in Photoshop.
    1) I use a wide gamut monitor, which LaCie says is 95% of Adobe RGB. According to a 3D profile mapping viewer I have, when I view one color space over the other, that's pretty accurate. I much prefer to use my monitor profile as my working RGB space. Then I absolutely know the color I'm viewing is not being clipped off. Everything is pulled into the color space I'm viewing. Why is this important? Say you shot something that was a very hot pink. That color may be in the range of Adobe RGB, but not your monitor. Your monitor space just clips that pink to the closest pink it can display. Now you get a new monitor with a better color range. That same image will look very saturated compared to your old monitor. And not just pinks, anything that Adobe RGB was carrying your old monitor couldn't display. People's faces may be glowing pinkish red, where they weren't before. Had you used your previous monitor's profile as your working space, it could be converted to the new monitor's space in Photoshop. The end result would be that you would hardly see any difference at all. I won't use a color space that my monitor can't represent. You're working blind in reference to color your viewing as opposed to what the file actually has in it.
    2) Use a large color space such as Adobe RGB regardless of your monitor's ability to display it. Advantage? You're not throwing any color out that your camera captured. Personally, I don't care. The color I can view is already incredibly saturated. Far more than any printer or even photographic paper can reproduce. What I may lose isn't anything to lose sleep over. Disadvantage? Some of what you're seeing. The embedded profile is NOT what you're viewing. When you send to the printer, it's sending color data based on the working color space, not your monitor's space. How you've calibrated your monitor (white point, gamma, luminance, etc.) can result in the printed output being a little different to a lot.
    So there's give and take. Use your monitor profile as your working space and give up some of the original camera data, or work in a color space that is converted to your monitor's space and hold the original color data.
    I like what I see on the monitor but sometimes I hate what I see coming off my printer.
    I'm not sure if you mean colors are actually visually off (like greens print much redder than what you're viewing), or colors are generally accurate, but some are very dull compared to the monitor.
    If the former, an inaccurate monitor profile is the most likely cause. Though it can also be using the wrong printer profile for the paper being used. Even if you have the right printer profile, it's a profile based on the printer (even though it's the same model) they used to create it. Your printer's print head is likely not laying down ink in exactly the same manner (which is nothing unusual).
    If the latter, there's just a lot of color in RGB that cannot in any way be reproduced by fixed hue colorants on paper. Generally, the more saturated, wowwy zowwy color on screen, the less likely you'll get that on any kind of paper.

  • Default Color/pattern Palettes in CS 3

    In CS 2 and previous version, you could replace the default RBG or CYMK palettes to get a customized color and pattern pallet that comes up each time a new document is opened... I can't find those default files in CS 3? Have they moved or is there another way to accomplish the same thing in the newer version?

  • LR Color Management - Calibration and Monitor (not your typical post)

    Hi everybody,
    I see that there are still many issues around color management and printing in LR. I have had similar problems in past and Im still trying to work though them. The most touted problem is not calibrating or having a bad monitor profile. Well, I have tried calibrating my display with worse results. I get better results with an un-calibrated display, not exact results, but closer than with a calibrated display. My only computer is a Dell Latitude D830 with an LCD display and Nvidia Quadro 140M graphics card with a Spyder2 Suite calibration tool.
    After doing a fair bit of research online and speaking to other photographers (pro and amateur) Ive learned that laptop displays are notoriously difficult to calibrate due to their inability to display a wide range of color and contrast. There is also no way to adjust white point, RGB or any other setting on my display, only brightness and contrast. (perhaps a big part of the problem?)
    I was told that only high end displays (NEC, LaCie, Eizo etc @ $1000,00 this being the low end, and up) were the only way to get accurate colors. Others had said that LG and Samsung make a decent display at the $300.00 price point that would deliver good results but not pro level color management. Other than that go, back to an old CRT display. What is a semi-pro level display that renders excellent color that I wont have to re-mortgage my house to pay for?
    So heres my question to all of those who have said you need to calibrate and you have a bad profile can you please tell us your system set up (i.e. display, calibration tool, room lighting and set up etc..)?
    Im really interested in what you are doing more, better or differently than everyone else.
    Thanks,
    DC

    >Im really interested in what you are doing more, better or differently than everyone else.
    Nothing much. Same calibrator in addition to another Huey Pro which gives almost indistinguishable results. I use both a Apple Mac Book Pro and a Mac Pro with a 30" DELL wide gamut adobeRGB display. Colors on the two are identical (if they're not outside of the laptop's gamut) and identical to prints from labs and direct prints. Of course these displays are between far better and quite a bit better than the display on a typical Dell laptop that are notoriously bad. One of the things I have to do on the laptop is to get the display at the right angle. The trick I use is to have a window open with this image: http://www.normankoren.com/monitor_test_txt22.png
    from this website: http://www.normankoren.com/makingfineprints1A.html
    If you're looking at your monitor at the right angle and you have calibrated the display correctly, the color should look homogeneous (i.e. completely neutral and the same grey everywhere). If you cannot find an angle at which this is correct, than it is likely your monitor can simply not be calibrated or that your calibrator is defective (there was a batch of defective Spyders a while ago). In general, it is certainly not true that laptop displays cannot be calibrated.
    >I was told that only high end displays (NEC, LaCie, Eizo etc @ $1000,00 this being the low end, and up) were the only way to get accurate colors.

    They are quite wrong and a rather snooty thing to say. The point of these high priced displays is that they will give better color in [B]non[/B]-colormanaged applications, but with a good calibrator, a reasonably good screen and [B]correct color management [/B](such as that in Lightroom, Photoshop, preview.app, Safari, etc.) you will get about as good color as the more expensive displays. Some of these, such as the EIZO give you wider gamuts higher bit color, or hardware adjustable white point, which are also a major selling points if you're doing very critical work but only if paired with good calibration and managed apps. Pro level color management is a function of the calibrator and the software - and only in part of the display. Most displays, with a few exceptions, can be made to give good color, as long as you use a hardware calibrator and managed apps.

  • Test color patterns on product packaging

    We were discussing print design media in a class yesterday and somebody asked why there are what appears to be color test patterns on some product packaging. For example, the box of tea that I have sitting in front of me at the moment, has one of these patterns printed on one of the inner flaps of the box. Can anybody explain to me the reasoning for having these test patterns included on actual product packaging material? Thanks.

    You're welcome.  It's actually a very good question.  I think the majority of consumers just ignore them, but they are key in production.
    Typical offset sheetfed print jobs have them along the width of the press sheet.  Those can be used to maintain proper ink densities along the full width and depth of the sheet, as well as maintaining color registration ( alignment ).  But, in sheetfed, they are trimmed, tossed and never seen by anyone.
