】In order to solve the problems that the existing motion detection algorithm in surveillance system can not work well in complex outdoor scene, and needs too much computation and memory, this paper proposes a moving objects detection algorithm based on improved codebook model. Pixels are converted from RGB space to YUV space to build the Codebook Model(CBM), and then the luminance component of each codeword is modeled by Gaussian model. The image is morphological processed by connected components algorithm. A test with the typical video sequences and the analysis of ROC data prove that the algorithm is effective and practical, and it can easily be implemented in embedded system such as DSP and FPGA.
