meanshift图像跟踪算法，实现目标物体的连续跟踪-meanshift image tracking algorithm to achieve continuous tracking of the target object

MEANSHIFT算法，里面主要包含：目标尺度不变、增量试探法、多级正方形法；-MEANSHIFT algorithm, which mainly includes: the target scale invariant, incremental heuristics, multi-level square law

使用mean shift算法实现图像分割，先将图像扩展，而后实现分割-Using mean shift image segmentation algorithm, first image expansion, then realize segmentation
