Feature fusion in multimodal recognition based on ear and profile face

Because of ear's special physiological structure and location, it is reasonable to combine ear with profile face for recognition in such scenarios as frontal face images are not available. In this paper, a novel method of multimodal recognition fusing ear and profile face based on kernel principal component analysis is proposed. With the algorithm, the fusion feature vectors of ear and profile face are established and nonlinear feature fusion projection could be implemented. The experimental results show that multimodal recognition fusing both ear and profile face results in improvement over either ear or profile face unimodal recognition.
