I worked on a joint project with the Swiss Center of Electronic and Micro technology (CSEM). The project aimed at controlling a mobile miniature camera using original image processing and control algorithms taking their roots from biology.In order to find such algorithms, we have deeply studied the visual oculomotor behavior of verterebates and specially primates. We have particularly studied the miniature motions and the saccades. First, we think that some miniature motions of the eye called the tremors have an important contribution to the low level vision. This high frequency (30 Hz - 100 Hz) and small amplitude motion help us to have a stable perception of the world. Second, the saccades are an important contribution to the perception of space. The saccades are partially volunteer high speed motion of the eye that are firstly compensating the non-uniform receptor density of the retina.
We are using this two principles of the oculomotor system to extract stable features from the visual world using a specialized frame-grabber and to orient an autonomous robots : the Koala for navigating in an indoor environment.
