–Ce travail est basé sur une architecture particulière de rétine CMOS, que nous avons baptisé « rétines à masques ». La fonction primaire de ces rétines est la mesure de corrélation entre une image et plusieurs fonctions binaires appelées « masques ». Nous montrerons dans cet article qu'un choix adéquat des masques permet un calcul de moments géométriques(More)
We present in this paper a method for implementing moment functions in a CMOS retina for object localization, and pattern recognition and classification applications. The method is based on the use of binary patterns and it allows the computation of different moment functions such as geometric and Zernike moments of any orders by an adequate choice of the(More)
We present a 64-ϫ 64-pixel CMOS image sensor chip that can acquire a 16-gray-level image containing both spatial and temporal information of the moving luminous object under observation. The image can next be processed using any image processing software in order to determine the speed, trajectory, and direction of motion of the moving object. The(More)
