A Novel BiLevel Paradigm for Image-to-Image Translation

no code implementations18 Apr 2019 Liqian Ma, Qianru Sun, Bernt Schiele, Luc van Gool

Image-to-image (I2I) translation is a pixel-level mapping that requires a large number of paired training data and often suffers from the problems of high diversity and strong category bias in image scenes.
