Adaptive Codebook Model Background Update Algorithm
Liu Shulinb · Video Engineering · 2013
Codebook model is a widely used method for video object detection and its performance is dependent on the quality of background model.Existing update algorithm can't work well when the object motion is sparse and insufficient.They lead to misjudgments in processing slow-moving objects and only the local moving object.To solve the problem,a new method was presented.The method gets the moving object spatial information and then joint pixel time-domain statistical information to complete background update.Experimental results show that this algorithm not only adapts to environmental changes but also can handle the limited object motion and ensure the integrity of the moving object.
