Fast template matching tracking algorithm based on image separation block processing

The application scope of traditional template matching tracking algorithm is limited because of its large computation load and poor real-time performance. In order to overcome this problem, it shall be optimized to meet the real-time requirement. A modified real-time imaging tracking algorithm based on the available position prediction relevant tracking algorithm is presented by utilizing the image block processing to decrease the calculation load of traditional correlation tracking algorithm and improve the real-time performance. The modified algorithm was simulated and verified in the experiment. The result of simulation indicates that the presented algorithm decreases the matching calculation load and improves real-time performance, reduces the effect of the stochastic noise and makes tracking faster and accurate.
