Large Margin Coupled Mapping for Low Resolution Face Recognition

Summary: Traditional face recognition algorithms can achieve very high performance in a well-controlled environment. However, when the resolution of facial images changes, the performance of these algorithms is very low. A two-step framework was proposed to solve the resolution problem by using super-resolution (SR) and face recognition on super-resolution face images. However, when SR focuses more on visual enhancement than on classification accuracy, the method's performance in identifying tasks is usually lower. Recently, Collage Mapping (CM) with different resolutions has been introduced into the face recognition framework, which learns the common feature subspaces of a high-resolution (HR) and low-resolution (LR) face image. In this paper, inspired by the maximum edge projection, we propose a large-scale coupled mapping (LMCM) algorithm to learn to predict to maximize the inter-class distance between objects and in public spaces. Experimental results from the public FERET and SCface databases show that LMCM is effective for low-resolution face recognition.
