      Face sketch-photo synthesis plays an important role in law enforcement and digital entertainment. Most of the existing methods only use pixel intensities as the feature. Since face images can be described using features from multiple aspects, this paper presents a novel multiple representations based face sketch-photo synthesis method that adaptively combines multiple representations to represent an image patch. Specifically, it combines multiple features from face images processed using multiple filters and deploys Markov networks to exploit the interacting relationships between neighboring image patches. The proposed framework could be solved using an alternating optimization strategy and it normally converges in only five outer iterations in the experiments. Our experimental results on the Chinese University of Hong Kong face sketch database, celebrity photos, CUHK Face Sketch FERET Database, IIIT-D Viewed Sketch Database, and forensic sketches demonstrate the effectiveness of our method for face sketch-photo synthesis. In addition, cross-database and database-dependent style synthesis evaluations demonstrate the generalizability of this novel method and suggest promising solutions for face identification in forensic science.
