(for fun, perhaps ;) As it is, pix_blob works quite well - and if you need multiblob, update pd/gem from CVS - pix_multiblob works very well also, and is quite fast. *instancing* / id tracking is rare (not inherent to openCV either), but I was able to hack it well enough for my purposes. > if nothing else works, it might be simplest to just write your own > application (without pd) and send the data to pd via your favourite > protocol (FUDI, OSC, SMTP...) Indeed - for more complicated operations (face & body recognition) I used opencv's haars, then sent the coordinates to GEM via OSC for various visual effects. >From pd context, I don't see what benefit opencv blobs have over pix_multi/blob; but perhaps I am missing something! _______________________________________________ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
