摘要 细胞局部二值模式(cell structured Local Binary Pattern)不能将人体图像的局部信息与全局信息相结合。针对这一不足,在细胞局部二值模式特征的基础上,提出多尺度细胞局部二值模式(Multi-scale cell structured Local Binary Pattern,MLBP)特征描述子,联合局部与全局信息,增加检测特征的信息量;另外,在MLBP的基础上进一步提出一个控制因子调节的新算子—可调多尺度细胞局部二值模式(Adjustable Multi-scale cell structured Local Binary Pattern,AMLBP),利用控制因子选择MLBP的最佳表征,提高人体检测的准确率。实验结果表明所提出的两个新特征较前人提出的特征更有效。 The cell structured local binary pattern （LBP） can not combine local and global information together. Therefore, propose multi -scale cell structured LBP （MLBP） to explore the full strengths of them by local and global information. Also extend MLBP with a con- trol factor and thus obtain a new feature descriptor called adjustable multi-scale cell structured local binary pattern （AMLBP） where the control factor is utilized to select the best description of MLBP,so can further improve the detection accuracy. Experimental results dem- onstrate the efficiency of the proposed methods.
