Abstract: Correlation tracking technology plays an important role in image tracking. A tracking method based on joint transform correlation was studied. Adjacent frames in image series were sequentially operated, then the position of the correlation peak and the time interval of adjacent frames were obtained. These data enabled us to get the changes of target in position, direction and velocity. Simulation results show that the proposed method solves the problems in traditional algorithms which have accumulated errors and are easy to make targets drift out of the reference template , and can recognize and track the target steadily based on joint transform correlation.
