Re: [PD] tracking multiblob with constant ID

I remember looking into pix_blobtracker but I don't remember why I didn't use it. In any case, I wrote a Pd abstraction last weekend which I called nearest-neighbor which I think might do the same thing: it looks for the shortest euclidean distances between blobs of the current frame with blobs of

Thanx Max but i never make an external for Pd from c++. The example with ping-pong balls is what i am looking for. Jaime, your external seems to be what i need, but i am a newbie in compiling stuff. When i enter : $ make i get : make: *** No rule to make target `.pd_linux', needed by `pd_linux'. S

Hey Jack, I use versions of this object [tracks] for my stuff: http://www.jaimeoliver.pe/archives/741 I know William is working on a new object for this same purpose and in doing so he caught a bug in mine and several opportunities for optimization. The object should be working however. Let me kn

[PD] tracking multiblob with constant ID

Do you know if there is an external to track multiblob with a constant ID (the ID doesn't change in the time when two or more blobs move). For example, with [pix_multiblob], the ID of the blob is given by its position relative to the lower left corner (or i'm wrong), so it is not good for my applic
