Research on video coding parameters affecting object tracking

Researchers have done a great number of studies on the visual object tracking and the video encoding transmission respectively. However, there are still no public reports about the influence on the visual object tracking raised by the video coding rates. In this paper, for this issue, a typical tracker with the features of HOG and the most commonly-used video encoding methods-H.264/AVC, are chosen as the test objects. In order to study how the code rates affect the performance of visual object tracking, the tracking experiments under different code rates are designed and the function of tracking performance is caused by the code rates. The result shows that the compromise can be achieved between the channel bandwidth and the visual object tracking performance through selecting the appropriate code rates for the encoder which provides basis for encoding optimization object function of different video applications.
