结合背景更新和亮度范围的改进Codebook模型算法
IMPROVED CODEBOOK MODEL ALGORITHM COMBINING BACKGROUND UPDATE AND BRIGHTNESS RANGE
摘要
Abstract
Traditional Codebook background modelling algorithm is established in RGB colour space,it has the problems of complex calcu-lation,low segmentation quality and poor anti-jamming capability.In this paper,we first built the Codebook background model by utilising the characteristics of luminance and chrominance separation of YUV colour space.Secondly,we used the mean of Y component of codeword in Co-debook to redefine brightness range aimed at the problem of unreasonable definition in brightness range of background model.Finally,in the process of moving object detection we employed the background update method combining two-layer Codebook and short-sliding window to im-prove anti-jamming capability.Experiments showed that the brightness range in improved algorithm can update gradually with the background changes.Compared with traditional Codebook background modelling algorithm,this one can effectively update background and meanwhile im-prove detection accuracy as well.关键词
