Based on the high speed TV,the obtainment of the self-adaptive threshold was introduced,which was very important to automatic target tracking.At the same time,the three tracking ways such as Center Tracking,Correlation Tracking and Integrate Tracking had been put forward,which could be used to track some given objects that likely had varied shape,abnormal acceleration and quite high speed.Experiments revealed that these tracking ways are stable,available and compatible with much reference and application value in the related field such as the design and realization of Automatic Target Tracking System in High-speed TV.
