I'm writing here to get some help about pd tracking objects (pix_blob..). I'm using the background subtraction method, to track objects and I need help to understand how I can track multiple objects with multiples different blobs. I'm trying the pix_multiblob and yes, it show 2 blobs..but they track the same object. Then basically I do not understand how can I make the first blob to follow just one object for all the time that specific object is inside the webcam rectangle, and the second blob to track another separate object. I cannot find any material that clearly talks about this.I attached the patch I'm working on. I'd love to see some well-explained examples if you know where to get them.
