Face sketch-photo synthesis and recognition: Dual-scale Markov Network and multi-information fusion.

Sketch face recognition (SFR) has been widely and successfully applied in law enforcement, which attracts a growing number of researchers. In this paper, a face sketch-photo synthesis and recognition method is proposed. Our method has two parts: Firstly, according to the different synthesis results for different scales, a cascade sketch-photo synthesis method via dual-scale Markov Network is utilized for image synthesis; Secondly, structural information and feature information-based data fusion method has been presented for face recognition. It is inspired by the Face Recognition Cognitive Theory, which applies both structural information and feature information for recognition. The experimental results on different databases based on the proposed method, demonstrate the outperformance of our method compared with state-of-the-art methods both in synthesis and recognition processes.
