[PD] Tracking color with GEM+Pdp

[Olivier Baudu]

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

>> 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.
