Abstract: In order to effectively extract the global and local features to improve the performance of face recognition, this paper presents a robust yet simple feature extraction method, called multi-scale image decomposition based on local structure. In the algorithm, the face image pyramid is first constructed through a multi-scale analysis. Then the local structural information by describing the relationship between the central macro-pixel and its neighbors for each level of the image pyramid is captured. In this way, one image is actually decomposed into a series of sub-images. Finally, all the structure images, after being down-sampled, are concatenated in one super-vector. Experimental results show that the proposed method is superior to some traditional methods such as Gabor, LBP and IDLS.
