【Abstract】 The ability of Sensing change and movement in the visual environment comprises one of the important bases for the brain intelligence. This paper includes two parts: i) a computational model for visual moving image filter, i i) a fuzzy algorithm for detecting visual motion direction of moving object. We conducted both computer simulation and real-time simulation for the proposed model and the fuzzy algorithm. A biological plausible "electronic neural network setup for real-time processing motion image information "has been built We propose that human visual motion direction detecting system may be a fuzzy system. Using the fuzzy algorithm the correct detection of moving direction for a moving object can be realized conveniently. Our real-time simulation results show that the detected moving object image is in high resolution with lower level noise and real-time tracking object moving in the plane perpendicular to the sensor is possible.更多还原
