| 摘 要： | 掌纹识别一般的预处理过程,是通过图像二值化、边缘检测、子图截取等步骤,获取掌纹感兴趣区域（RIO）,截取掌纹子图。给出一种基于最大内切圆的子图截取算法,并对该算法进行优化,通过平移和旋转校正,得到掌纹RIO区域子图。

| Abstract: | This paper describes a general pre-palmprint identification process,through image binaryzation,edge detection,interception and other sub-graph steps,acquire palm region of interest（RIO）,interception of palm sub-graph.Emphasis is given based on the largest inscribed circle of the sub-graph intercept algorithm and the algorithm is optimized,through the translation and rotation correction,to get palm RIO region subgraph. |
