摘要：The perimeter of an object is detected using a CCD. When a pixel is dark a right detection turn is taken and when a pixel is light a left detection turn is taken. When a transition from light to dark or from dark to light occurs the address of the light pixel is recorded to identify the light pixel as a perimeter pixel.
