Hi, I'm trying to use some patches Max Neupert has published, to track motion. The patches use [pix_movement], [pix_background], [pix_blob] and other objects (not all of them in all the patches). I can track white for now fine, but can't really find out how to track green, for example (well, the actual color I want to track is greenish). Any suggestions on how to do this?
hi!
use pix_rgb2hsv to convert to hsv colorspace. then use pix_curve with 3 different tables for hue, saturation and value to filter out the desired color. then convert back with pix_hsv2rgb. it's a little bit of experimenting with the curves...

you may also want to take a look at pix_colorclassify, its help file and associated demo.

PS: btw, pix_colorclassify actually does exactly what you want. It supports Greenish, Red-ish, Yellow-ish, Blue-ish, Black-ish and White-ish ;) And it has been extensively developed and tested using a large database of real colored paper photos under different illumination conditions. You may need a very recent GEM.

Just remembered a short video demo of tracking greenish in pd, as you asked:
* *http://vimeo.com/rfabbri/color-joystick
It uses pix_colorclassify. I am actively maintaining this so if you have any trouble using it just let me know. Hope it can be useful in your case.
