Handmetric Verification Based on Feature-Level Fusion
Qiang Li, Zhengding Qiu · 2006
Summary This paper presents a multimodal biometric system called “handmetric”, which is the fusion of hand based biometrics including palmprint, knuckleprint and hand shape. Moreover, a new framework of FLF (feature-level fusion) is put forward based on subspace analyzes. While verifies that existing feature concatenating methods are instances of the framework, a parameter optimized model using KPCA (kernel principal components analyze) is presented and applied to the verification system. The experiments testify the effectiveness of proposed method.
