You can change the lens on the SRV-1 Blackfin camera.  Default lens is 3.6mm focal length with 90-deg field of view, but any 12mm diameter lens with 0.5mm thread pitch will work.  Here are some options -

There's basic blob tracking now, but you will probably need some additional filtering for shape and perhaps motion estimation.  Certainly, the processor has the capability to perform this type of operation, but the software is important.

So it's about software and not about hardware?  :D I hope it is, software is *free* lol but hardware ain't  :(

Yes - it's about software.  With the SRV-1 Blackfin camera, the hardware will capture camera frames into memory at close to 30 frames/second using DMA (no CPU load), even at 320x240 or 640x480 resolution, so then it's a matter of telling the Blackfin what to do with the pixels in software.

Awesome! So blackfin + roborealm = Succes  ;)
However I'm a bit short of money lol so I'll look for other "alternatives"

Thanks
