Query: Unsupervised Facial Geometry Learning for Sketch to Photo Synthesis   Face sketch-photo synthesis is a critical application in law enforcement and
digital entertainment industry where the goal is to learn the mapping between a
face sketch image and its corresponding photo-realistic image. However, the
limited number of paired sketch-photo training data usually prevents the
current frameworks to learn a robust mapping between the geometry of sketches
and their matching photo-realistic images. Consequently, in this work, we
present an approach for learning to synthesize a photo-realistic image from a
face sketch in an unsupervised fashion. In contrast to current unsupervised
image-to-image translation techniques, our framework leverages a novel
perceptual discriminator to learn the geometry of human face. Learning facial
prior information empowers the network to remove the geometrical artifacts in
the face sketch. We demonstrate that a simultaneous optimization of the face
photo generator network, employing the proposed perceptual discriminator in
combination with a texture-wise discriminator, results in a significant
improvement in quality and recognition rate of the synthesized photos. We
evaluate the proposed network by conducting extensive experiments on multiple
baseline sketch-photo datasets.
