"WebMean Shift is also known as the mode-seeking algorithm that assigns the data points to the clusters in a way by shifting the data points towards the high-density region. The highest density of data points is termed as the model in the region. It has applications widely used in the field of computer vision and image segmentation. " - Opencv meanshift c++视频跟踪
