An anonymous reader writes "Researchers from the University of Liege in Belgium have been able to perform real-time video analysis on a regular Canon digicam (video link) without any hardware modification. The results are shown directly on the digicam's screen. They use a hacked version of a popular open-source alternative firmware for Canon cameras: CHDK. This is a proof-of-concept that computer vision algorithms can now be embedded on regular Canon digicams with little effort (CHDK is coded in C). What other popular vision algorithms could be implemented? For what purpose?" You can get some idea about ViBe from this abstract at IEEE; basically, it allows background extraction in moving images.
