Abstract

In order to improve the identification accuracy and the robustness by using collection information of the image set, and hence greatly reduce the influence of posture, light, misalignment and so on, this paper developed a novel method, called learning prototype set and orthogonal projection for image set classification(LPSOP), which simultaneously learnt the representatives(prototypes) and a linear discriminative projection for each image set, making any image set in the target subspace can be classified into its nearest neighbor prototype optimally. In addition, the learned representatives not only reduced redundant image noise but also reduced the consumption of time and memory. At the same time, the projection matrix greatly improved the classification accuracy and noise robustness. Experimental results on UCSD/Honda, CMU MoBo and YouTube databases prove that compared to state-of-the-art learning methods, LPSOP has higher recognition accuracy and better robustness.
