Abstract :
This paper describes a new parallel architecture dedicated to multi-motion estimation. The input image is scanned by a standard video camera with 256 grey levels. Motion computing is based on the optical flow determination. Some constraints are proposed to allow multi-motion evaluation. The algorithm is presented and the main features of a 1-D systolic architecture which is based on a custom VLSI chip is given. This architecture allows a real-time implementation of the multi-motion estimation algorithm
