掌纹的自动定位与分割技术

提出了一种新的掌纹定位与分割技术,该技术所涉及的主要工作包括:掌纹图像的边界跟踪、手掌无名指与小指内侧边缘的直线拟合、2拟合直线角平分线的求取、掌纹自动定位与分割直角坐标系的最终建立,以及感兴趣目标的分割.实验结果证实了该方法的有效性.

Research on Palmprint Automatic Positioning and Dividing up Technology

A new technology of positioning and dividing up is proposed in this paper.The technology is mainly related to such works as follows: border tracing of palmprint image;fitting the inner border of the little finger and the ring finger by using the straight-line;computing the bisector of the two straight-lines;and final establishment of the palmprint positioning and segmentation coordinate system and dividing up of the target area being interested in.The result of the experiment confirms the validity of this method.
