Fast Face Sketch–Photo Image Synthesis and Recognition

Abstract

Face sketch recognition has great practical value in the criminal detection, security and other fields. Especially, it can help the police narrow down potential suspects in criminal detection effectively. Face sketch represents the original photos in a simple and recognizable form, so sketch and photo are images of two different modes. In order to identify the corresponding sketch face image in a lot of photo face images, this paper presents an improved sketch–photo transformation algorithm, and it uses the effective characteristics of the photo image more reasonably during transforming a photo image into sketch. In this way, it can reduce the difference between the sketch and photo image to improve the matching effect, and save the recognition time. Many experiments on CUHK Face Sketch database including 188 sketch–photos prove the effectiveness of the method in this paper.
