摘要

Recognition of objects in a computer vision system requires extraction of the images of all objects. If the object and camera are moving then the task may be to extract images of only the moving objects. We discuss methods for combining information obtained from the positive, negative and absolute difference and accumulative difference pictures. We present an approach for the segmentation of dynamic scenes using information available in the difference and accumulative difference picture. In addition to the efficacy of the approach, a very attractive feature is the possibility of implementing it in real time using a special hardware.
