摘要
基于Clifford代数矢量积表示定理,本文提出一种新的掌纹提取方法。选取掌纹线上的一个点作为种子点,将该点的八邻域的点归一化后作为该点的8个特征,对图像进行遍历检测,设定阈值,判断每个点是否为掌纹线上的点。在实验中选取3个种子点,然后对3个结果进行融合。实验证明,该方法比传统方法提取的掌纹信息更精确。
A new method of palmprint extraction based on the representation theorem of vector product of Clifford algebra is proposed.With this method a seed on palmprint line is selected as a seed point and the eight adjacent points are normalized to be eight features of the seed point.Then the image is measured with ergodic theory and the threshold values are set to judge whether each point is the one on palmprint lines.In this paper three seed points are selected and the final three images are fused together.The experimental results show that the information extracted with this new method of palmprint extraction is better than the traditional ones.
