Real-time Video Target Tracking Based on Improved Mean Shift Arithmetic
A video target tracking system is designed which is achieved in the embedded platform. The system acquires video signal by using CMOS image sensor, controls video signal in ARM9 processor which is obtained in Z228 multimedia chip, and compresses video signal through MPEG-4 hardware encoder. Meanwhile, the Mean Shift arithmetic is used to track moving target. Considering the convergence limitation, multiple search point is set to improve the tracking results. The operating speed of code is raised through decreasing sampling point and labeling computed points, thus the tracking instantaneity is enhanced. The experiment results indicate that this system can achieve video target tracking continually and steadily at the speed is 27 fps.
