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....<br><br>Best regards<br><br>José<br><br><div class="gmail_quote">

Hi,<br><br>I would like to track different colors at the same time with my web cam so I've try different way.<br>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.<br>
With two, it begun more complicate to configure [pix_alpha] in RGBA to dissociate the spots.<br>So, I've tried [pdp_ctrack] which is very powerful but in some situations it would be better to process only with moving pixel.<br>
<br>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...<br>
(By the way, I can't have simultaneously my webcam in GEM and in Pdp with [pix_2pdp], but, maybe, it's normal)<br><br>What can I do ?<br><br>Is there a [pix_movement] for Pdp I didn't find yet ?<br>Is there a way to chose precisely the color to configure [pix_alpha] ? (maybe by converting the colorspace with
<br>[pix_rgb2hsv] but what to do after ?).<br><br>Of course, if you have a solution for tracking color without answering my questions, I'm still interested. :-p<br><br>Thanks.<br><br>01ivier<br><br><br>
