Abstract: TLD algorithm is a long-term tracking algorithm for single target.And it has drawn wide attention recently.It can recognize target even the target that has been lost.However,its real-time performance is not good because of a large number of scanning boxes.We proposed a method which can generate scanning boxes dynamically.This method can reduce the calculation time efficiently and thus make TLD suit real-time situation.Experiment were conducted to compare the performance of the improved algorithm,original algorithm,Camshift and CT(Compress Tracking) algorithms.The experiment results show that when they are applied to real-time camera,the improved algorithm has faster tracking speed and higher accuracy.When they are applied on picture sequences,the speed and accuracy of the improved algorithm are better than other algorithms.
