摘要: 针对构建鲁棒的背景模型和背景模型更新问题,结合ViBe算法提出了一种基于生物视觉特性的背景减除算法.首先,借鉴蛙眼视觉外部特性中的近视特性,阐述了“区域模糊化理解”预处理操作的含义及其实现;其次,从人类对颜色的心理认知特性出发,给出了一种LUV颜色空间中基于韦伯定律的颜色差异度量准则;最后,从背景建模、前景检测以及背景模型更新三个主要方面,介绍了算法的具体实现.实验结果表明,该算法能够提高运动目标检测的精度.

关键词: 生物视觉, 区域模糊化理解, 韦伯定律, 背景减除, 运动目标检测

Abstract: For the problem of how to build a robust background model and update the background model, a background subtraction algorithm based on biological vision characteristics combined with the ViBe algorithm was proposed. Firstly, utilizing the extrinsic nearsightedness characteristic of the frogs visual system, the meaning of a pretreatment method called “region fuzzy” and its implementation were described. Then, considering the characteristics of color cognition by humans, a measurement criterion for color difference based on Webers law in the LUV color space was given. Finally, specific implementations of the algorithm were introduced from three main aspects: Background modeling, foreground detection and background model updating. Experimental results show that this algorithm can improve the accuracy of moving object detection.

Key words: biological vision, region fuzzily understanding, Webers law, background subtraction, moving object detection
