Faster Blob Detection

hello,
i’m tracking a video image via the Contour freeframe plug. anybody knows if there’s a faster way to do this? i don’t need contour information, just the coordinates of distintive spots in the image and i think there’s some overhead when using contour (?).

google gave me this…
http://code.google.com/p/cvblob/

…there’s something called ‘Basic blob tracking’ in the features list.

You could try using the pipet node. There was a workshop on this at Node08:

The file could do with tidying up, but you’ll get the gist of it.
