On Hallucinating Context and Background Pixels from a Face Mask using Multi-scale GANs

Sandipan Banerjee, Walter J. Scheirer, Kevin W. Bowyer +1

We propose a multi-scale GAN model to hallucinate realistic context (forehead, hair, neck, clothes) and background pixels automatically from a single input face mask. Instead of sw…
