Moving target detection under complex background based on code book

Abstract

For intelligent video monitor system, how to detect the moving target accurately is a key problem needed to be solved. The problem is more serious when background is complex. This paper uses a method based on code book to segment the foreground and background to detect the moving targets under complex background. This method uses the threshold of the color distortion of and brightness distortion. It creates a code book for each pixel, and each code book includes one or more code words. Code book will be updated as same as code word. The experimental results prove that even if the movement and brightness of background changes, this method can detect the moving target effectively and has good robustness.
