Abstract
The video output of a camera 120 viewing an object 110 is connected to an edge finding circuit 130 and a centroid finding circuit 140. Each of these produces an output which crosses zero at a time corresponding to the edges of the object occurring in the video signal (130) or to the average of these (140). An edge is assumed to occur when the video signal crosses its median value, it is alleged that problems due to variations in illumination and gradual changes in signal level are overcome by this technique. <IMAGE>
