Abstract

Due to the numerous important applications of face images, such as long-distance video surveillance and identity verification, face hallucination has been an active research topic in the last decade. This paper makes a survey of approaches to high quality face hallucination by looking at theoretical backgrounds and practical results. The strengths and weaknesses of these approaches are identified to form a base for a new sparsity-based method for super-resolving mis-aligned face images.
