A moving object based on dynamic background extraction

Management, and then after the results of 176 of Jiamusi University ( Natural Science) in 2009 as a background mean of the final motion parameters for motion compensation according to the parameters . ■ ■ Figure 2, the video before and after the two outdoor experiments (a) before compensation (b) Figure 3 after compensation of the difference image before and after compensation used in the experiment Mortimer sdk2000 external video capture card and rI ℃ LDSP220x PTZ camera as a hardware test platform. In the experiment platform, the direction of camera movement can be obtained through the software , it will limit the scope of the search block matching motion direction in the region, thereby further reducing the search for a matching calculation. Experimental results show that after the limited scope of the search block matching , matching full search time reduced by 40 % or more. VC environment results show that this method is quick and effective , in the case of the camera can correct a variety of sports matches , able to adapt to real-time processing . Nang Nang Figure 4, before and after the two experimental video 2 Summary and Outlook In this paper, the background compensation methods are under the rotating camera for moving objects segmentation, experimental results show that the method can effectively carry out motion compensation in real time . ■ ■ (a) before compensation (b) compensation compensation in Figure 5 before and after the first article in the difference image method for the interference caused by the disparity can not completely filter out points ; Secondly, due to hardware limitations, this paper 's model is more Simple, and the entire pixel matching using match , did not use bilinear interpolation to improve accuracy. Future, the algorithm can be ported to DSP platform,[link widoczny dla zalogowanych], a better model of adaptive and join the bilinear interpolation to improve the matching accuracy.
