Camshift algorithm is often used for object tracking in video surveillance, which has a good real-time performance. Unfortunately, Camshift is a semi-automatic tracking algorithm, it needs to select the initial search window by manual, and the manual-selection will result in a target-selection bias. For this shortcoming, this paper presents an improved Camshift algorithm to automatically select a moving target. Firstly, the moving object is extracted by background subtraction and threeframe-differences method, then the location of extracted moving target will be taken as the initial search window for the Camshift algorithm, and finally the automatic tracking of the moving target is realized.
