Report Color detection in IMAQ Vision in Machine Vision and Imaging Posted April 6, 2010 · Edited April 6, 2010 by lovemachinez The function you are looking for is called "Particle Filter" but before you can use it you need to convert your image to binary. The image below shows how it can be done in vision assistant. If the image is color you will have to extract a color plane then do a threshold. Here is the script and the vi that vision assistant created for me blob filter.zip Good luck yeah, Thank a lot. by the way, if I got a binary image how can I convert it back to the normal image.
