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.

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.

K

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.

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 ?
Thanks
Solved!

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,
Rap Master

Given that the pattern matching VI is an IMAQ (Image Acquisition) VI, this question will be best served by posting in our Machine Vision forums.

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).

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?

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.

Alternate color pattern

Hi,
We are currently using oracle forms 6i client/server.
I have a form with 20 records on it. We would like the record color background to alternate between white and gray.
In other words... record 1 will be white, record 2 will be grey, record 3 will be white again, record 4 will be grey again...and so in.
In APEX this can easily be done but is there anyway in oracle forms 6i to do this?. I tried visual attributes but did not have much luck.
Thanks
Munish

Hello,
You can try one thing.
Create two VISUAL ATTRIBUTE one for GRAY and one for WHITE let say VA_GRAY and VA_WHITE.
Now in that block create one trigger POST-QUERY block-level and set item instance property for all the items which are being displayed on the canvas. like...
Trigger = POST-QUERY (Block-Level)
IF MOD(:SYSTEM.TRIGGER_RECORD,2)=1 THEN
SET_ITEM_INSTANCE_PROPERTY('BLOCK_NAME.ITEM_NAME',CURRENT_RECORD,VISUAL_ATTRIBUTE,'VA_WHITE');
-- Include all the items which are on the canvas for the detail block as above
ELSE
SET_ITEM_INSTANCE_PROPERTY('BLOCK_NAME.ITEM_NAME',CURRENT_RECORD,VISUAL_ATTRIBUTE,'VA_GRAY');
-- Include all the items which are on the canvas for the detail block as above
END IF;And if there is insertion also in the same block then use the same code also in WHEN-CREATE-RECORD trigger on block-level.

Black has red lines and strange red color pattern in it!

I have an HP Touchsmart 520 - 1030 windows 7 all in one. When I turn on my computer and the Windows icon in the middle of the screen appears what should be a black backrground behind the icon is dark red. Once it boots up completely, everything black has a strange red lines and patterns in it.
Is there a fix for this?

Hi Lysa13,
You could try re-installing the graphics driver. If that doesn't work, it's possible the screen hardware could be starting to have problems.
Here is a link to the graphics driver:
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=cp-98005-1&cc=us&dlc=en&lc=en&...=
If that doesn't work, you may want to try running a screen test in the hardware diagnostics. Here is a support document that explains how to do the tests:
