ola,
have a look at the color filter from pix_opencv/pdp_opencv :

Oups...
I forgot to say it, but, of course I use [pix_blob] at the end of my
GEM chain...

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.
