摘要 侧抑制是神经系统信息处理的基本原则之一。空域侧抑制原理已广泛地应用于图象处理中。通过对同时具有方向和速率选择性的视觉皮层运动区神经元的时域侧抑制机制的模拟，提出了一种新的乘积抑制速度检测子（ＭｕｌｔｉｐｌｉｃａｔｉｖｅＩｎｈｉｂｉｔｏｒｙＶｅｌｏｃｉｔｙｄｅｔｅｃｔｏｒ，ＭＩＶＤ），其时空联合参数Ｋ决定了检测子的最优检测速度，它良好的速度选择性使它可以成为一个很好的速度识别算子。 Side inhibition is one of the basic principle in the nervons system information processing. Space domain side inhibition principle has been used widely for image processing. This paper puts forward a new multiplicative inhibitory velocity detector(MIVD) by simulating the time domain side inhibition mechanism of vision cortex movement area neurons with direction and velocity selectivity simultaneousty. Its time space combined parameters K decides the optimal detection velocity of the detector. Because of its better velocity selectivity, MIVD may become a very good velocity recognition operator.
