| 摘 要： | 基于掌纹的身份识别技术是基于人体参数身份识别技术的重要内容，如何选择合适的掌纹图象及其线特征，如何提取这些线特征是该项技术的关键所在，传统的边缘检测方法易产生双边缘，。易出现位置偏移，易受噪声影响，因此不适于掌纹线特征的提取，本文提出的一种基于形态中值金字塔的多分辨率线特征提取方法，借鉴多分辨率分析的思想，结合掌纹图象的特点及其相关知识来提取线特征，取得了较理想的实验结果。

| Abstract: | The personal identification technology based on palmprint is an important means to automated biometrics technologies and systems, in which how to select the proper line features and how to extract these features are the most challenging issues. There are three kinds of lines and curves in palmprint images, and these line features are the most important clues for identifying or verifying a person's identity. The traditional edge detection methods are not appropriate to palmprint images because of their shortcomings such as double_line edges, location offsets, sensitivity to noise and so on. The line feature extraction method based on morphological median pyramid presented here is well supported by experimental results. |
