Multiset Canonical Correlation Analysis: Texture Feature Level Fusion of Multiple Descriptors for Intra-modal Palmprint Biometric Recognition

This paper describes a novel intra-modal feature fusion for palmprint recognition based on fusing multiple descriptors to analyze the complex texture pattern. The main contribution lies in the combination of several texture features extracted by the Multi-descriptors, namely: Gabor Filters, Fractal Dimension and Gray Level Concurrence Matrix. This means to their effectiveness to confront the various challenges in terms of scales, position, direction and texture deformation of palmprint in unconstrained environments. The extracted Gabor filter-based texture features from the preprocessed palmprint images to be fused with the Fractal dimension-based-texture features and Gray Level Concurrence Matrix-based texture features using the Multiset Canonical Correlation Analysis method (MCCA). Realized experiments on three benchmark datasets prove that the proposed method surpasses other well-known state of the art methods and produces encouraging recognition rates by reaching 97.45% and 96.93% for the PolyU and IIT-Delhi Palmprint datasets.
