Sparse representation has been extensively applied to image recognition, while learning appropriate dictionaries for image content representation plays a critical role in it. An approach to simultaneously learn a common dictionary and multiple class-specific particular dictionaries achieves state-of-the-art performance. However, how to separate the particularity and commonality correctly is a quite important problem. Meanwhile, there exists an over-fitting phenomenon in the dictionary learned from given training samples which lie on a low dimensional subspace in that data samples can be linearly represented by dictionary. In this paper, we propose rank constraints on the joint dictionary learning (RC-JDL) algorithm to solve the above questions. Extensive experimental results on public available databases demonstrate the effectiveness of the proposed algorithm.
