掌纹识别中的尺度不变特征转换改进算法
Improved Algorithm of Scale Invariant Feature Transformin Palmprint Recognition
摘要
Abstract
Aiming at the problem that traditional Scale Invariant Feature Transform(SIFT) algorithm may cause error match in low resolutionpalmprint image, this paper proposes a novel approach of palmprint recognition based on improved SIFT algorithm. According to the thought oflocal match, the algorithm combines the Euclidean distance and weighted sub-region. The similarity calculated can reflect the local and globalfeatures of images. Simulation results prove that the recognition fate of the improved SIFT algorithm is higher than the recognition rate of SIFTalgorithm.关键词
