Yes, for sure... That's why my first message was dealing with "how to use [pdp_ctrack ] only with moving pixels ?" :-)

Hi, the best object for tracking color is pdp_ctrack.... works very.very fine... you can duplicate the program and track many colors....works really fine....
Best regards

Hi,
I would like to track different colors at the same time with my web cam so I've try different way. I begun in GEM with [pix_movement] and/or [pix_alpha] and/or [pix_background]. It was quite good until I wanted only one tracking. With two, it begun more complicate to configure [pix_alpha] in RGBA to dissociate the spots. So, I've tried [pdp_ctrack] which is very powerful but in some situations it would be better to process only with moving pixel.
I thought [pix_2pdp] would be the solution to use [pix_movement] before [pdp_ctrack] but it seem not to work with [pix_video] in RGBA colorspace, and in YUV I loose the color information after the [pix_movement] process... (By the way, I can't have simultaneously my webcam in GEM and in Pdp with [pix_2pdp], but, maybe, it's normal)
What can I do ?
Is there a [pix_movement] for Pdp I didn't find yet ? Is there a way to chose precisely the color to configure [pix_alpha] ? (maybe by converting the colorspace with [pix_rgb2hsv] but what to do after ?).
Of course, if you have a solution for tracking color without answering my questions, I'm still interested. :-p
Thanks.
