Abstract

Collaborative representation-based classification(CRC) has become a breakthrough in the field of face classification due to its effective collaborative capability. However, for some practical scenarios, it used few or even a single face image to address the issues such as illumination, expression, pose and occlusion changes, which might lead to inadequate capability for CRC. To solve this problem, this paper proposed a discriminative bi-directional CRC(DB-CRC) algorithm for image recognition. Firstly, it obtained a structured dictionary using Fisher discrimination dictionary learning(FDDL) model, in which the sub-dictionary of specific-class had robust representation capability for the samples of related-classes. Therefore, by means of larger inter-class and smaller intra-class scatters, the reconstruction error and coding coefficient could be described in discriminant manner. Then, it used the obtained sparse coding coefficients as the test samples for the bi-directional representation, and established a fast inverse representation model. It estimated the bi-directional reconstruction based residual information between each test sample and the structured dictionary via bi-directional representation strategy. Finally, this paper used the competitive fusion method to achieve the final classification result, by weighting and ranking the obtained reconstructed resi-duals from the bi-directional representation model. Experimental results conducted on a set of well-known face databases including AR, PIE and LFW verify the effectiveness of this algorithm, especially its robustness for small sample size problem.
