运动检测的目的是从序列图像中将变化区域提取出来。运动区域的有效分割对于目标分 类、跟踪和行为理解等后期处理非常重要，因为后期处理过程仅仅考虑图像中对应于运动区 域的像素。然而，由于背景图像的动态变化，如天气、光照、影子及混乱干扰等的影响，使 得运动检测成为一项相当困难的工作。-The purpose of motion detection from image sequence changes in the region will be extracted. Sports region segmentation for effective target classification, tracking and understanding behavior such as post-processing is very important, as post-processing the image corresponds to considering only the motion region of pixels. However, due to the dynamic changes of the background image, such as weather, light, shadow and chaotic interference effects, making motion detection into a very difficult task.
