experiment example
[0107] Five target part tracking videos taken in dynamic scenes were selected for experimental verification. The experiment was implemented using MATLAB 2012 under Windows 7 system, Intel(R) Core(TM) i5-2450M CPU@2.50GHz.
[0108] 1. Target tracking experiment
[0109] In order to verify that the method of the present invention maintains accurate and stable real-time tracking in complex environments such as background interference, light intensity changes, target motion blur, scale changes, and fast motion, 5 video segments in dynamic scenes were selected for experimental verification. These five videos contain background interference, light intensity changes, target motion blur, scale changes, and fast motion interference factors. The video parameters are shown in Table 1 below.
