Abstract
The programmable digital retina is an image sensor combining image acquisition and processing within each pixel. This work aims at building up a motion detection and analysis system based on this circuit while taking into account its limited memory and computing power.
We present three motion detection methods adapted to our constraints : first, a basic recursive mean-based background substraction ; then a statistical estimator, the Σ-∆ filter ; third, a variation amplitude detector, the forgetting morphological filter.
Then, we introduce an interest point detector which enables real-time mobile object pixel matching.
Through these examples we demonstrate the importance of the adquation of the algorithm design methodology with the specific features of the artificial retina.
