一种基于块的校正码书模型
Block based correction codebook model
摘要
Abstract
Complex dynamic background is very difficult for current moving object detection algorithms. This paper proposed a new block-based correction codebook model to solve this problem, where the correction codebooks were created based on pixel blocks in HSV color space. The merits of the new model lie in four aspects;a) introduced HSV color space to better distinguish the foreground and background;b) used the pixel block to build the codebook, and thus improved the detection performance with the affection of the variation of each single pixel ;c) presented a novel correction mechanism so that eliminated false targets efficiently ; d) also proposed codebook learning with small samples for fast detection. This paper further proposed a new performance evaluation method called recall-precision curve. The qualitative and quantitative experiments includes this evaluation method demonstrate that the proposed model can efficiently and quickly detect the moving objects under complex dynamic background.关键词
