Primary Ocular Movements Revisited

Vision is a very important issue developing artiicial anthropomorphic systems. Starting from traditional knowledge about ocular movements, mainly due to physiological observations , the paper revisits primary ocular processes and proposes some new ideas for oculomo-tor control. It is shown that using space-variant sampling, pursuit, vergence and saccadic process are considerably simpliied. The concept of binocular fusion is easily implemented and becomes very important in order to segment a candidate target from the background and perform continuous tracking over time. A set of experiments on real data demonstrates that space-variant processes can be fruitfully integrated in a simple hardware platform.
