How will you avoid gating the color of the object you're trying to track as
well?
To use your method below I'd suggest using some combination of [separator]
and [pix_background] to create a mask so that [pix_blob] (or the color gate,
depending on the setup) only affects new objects

at the moment this is rather a hack of your source then a proper
enhancement, but maybe, if you think this could be usefull,
a module lik c_track_matrix could be a goal. where one can send a list
with coordinates to track and the area space
surrounding that point
, if you don't use pdp_colorgrid,
no need for it.
i changed c_track in the source, so that it checks not one point, but
a matrix of points. at the moment all these points
are with fixed offset between each other. from pd i just set the start

Hi
You can completely do what you want on the GPU with a shader or
shaders. In fact, the very shader you describe exists from cycling74
and is included with jitter.
As for dealing with color planes, the RGBA values, its VERY easy to do
with shaders. You simply sample a texture with:
vec4
to trigger both the start of
the track in specimen as well as the video and recording in Pd. That's
basically the same patch that I use as "VJ bot" for DJing with friends.

I been seen that with opencv it is possible to track blobs based on
