结合局部二元图特征的运动目标阴影抑制方法
Shadow suppression method for moving object based on the characteristics of binary pattern
摘要
Abstract
An improved image segmentation algorithm which combining image edge information was proposed in order to solve the problem that the shadow discrimination algorithm based on local binary pattern texture works badly on dark shadow edges suppression .In shadows suppression step ,for the pixels on edges , the proposed algorithm clustered pixels into foreground and background based on their local binary pattern texture values directly ;for other pixels ,a sliding window with the undeter‐mined pixel as its center was used ,and the local binary pattern texture values of background pixel and foreground pixel at same place in the sliding window were compared .Then the number of pixel pairs with same binary pattern texture value among the sliding window was counted .If the number was greater than certain threshold ,then the center pixel was classified as background pixel ,otherwise it was classified as foreground pixel .The experimental results show that the improved algorithm is a‐daptive to shading degree change ,w hich can eliminate false shadow edges compared to the algorithms only using local binary pattern .The computation complexity is proportional to the size of the shadow area .关键词
