Abstract：Face sketch synthesis aims to transform a face photo into a face sketch. For existing methods, the generated sketches are over-smooth and the pre-training on additional large scale datasets is required. In this paper, a deep bidirectional network based on the least mean square error reconstruction(Lmser) self-organizing network is constructed with a feature of duality in paired neurons(DPN) to generate face sketch. DPN is realized with bidirectional shortcuts between encoder and decoder. It helps transfer features learn from different layers of the Lmser to improve texture details in synthesized sketch. Another sketch-to-photo mapping network is built by a complement Lmser with converse direction sharing the same structure. The bidirectional mappings form an outer Lmser network with DPN enforce consistency between the paired blocks in a global manner. Experiments on benchmark datasets demonstrate that the performance of the proposed method is superior, and it is more applicable and does not need pre-training on additional datasets.
