Palmprint recognition based on two-directional two-dimensional Fisher''s linear discriminant analysis
基于二维双向FLD的掌纹识别方法

A new method named two-directional two-dimensional Fisher's Linear Discriminant analysis was proposed for palmprint image representation and recognition. The method perform 2DFLD twice, one was in horizontal direction and the other was in vertical direction, so pertinency of rows and columns in palmprint image was avoided. The Fisher criterion was used to select the most discriminative features, and the discriminant information was compacted into the up-left corner of the image. Experiment results show that...
