一种改进的掌纹线方向特征提取方法

掌纹识别由于方便易行,近年来已成为鉴定人身份的主要方法之一.经典的基于线方向特征识别掌纹的方法忽略了纹线上其他具有辨别力的方向特征.该文改进了传统基于半方向特征编码的方法,改变其中一个半方向编码特征为另一个具有代表性的方向特征,获得了更多的掌纹曲线特征,从而有效提高掌纹识别效果.实验表明,该方法相比传统的方法具有更高的识别率及准确度.

The Improved Approach of Palmprint Feature Extraction via Half-Orientation Code

Palmprint recognition has became one of the most popular methods for identifying a person in recent years due to its high convenience and ease of use.The classic methods of palmprint identification are generally based on the orientation of the lines ignores the other discriminative orientation features on the ridge lines.This paper proposes an improved half-orientation code method,which changes one of the half-orientation features to another representative half-orientation features and obtain more features of palm lines.Experimental results show that the proposed method can achieve a higher recognition accuracy than the conventional method.
