Query: On Hallucinating Context and Background Pixels from a Face Mask using
  Multi-scale GANs   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 swapping a face on to an existing picture,
our model directly generates realistic context and background pixels based on
the features of the provided face mask. Unlike face inpainting algorithms, it
can generate realistic hallucinations even for a large number of missing
pixels. Our model is composed of a cascaded network of GAN blocks, each tasked
with hallucination of missing pixels at a particular resolution while guiding
the synthesis process of the next GAN block. The hallucinated full face image
is made photo-realistic by using a combination of reconstruction, perceptual,
adversarial and identity preserving losses at each block of the network. With a
set of extensive experiments, we demonstrate the effectiveness of our model in
hallucinating context and background pixels from face masks varying in facial
pose, expression and lighting, collected from multiple datasets subject
disjoint with our training data. We also compare our method with two popular
face swapping and face completion methods in terms of visual quality and
recognition performance. Additionally, we analyze our cascaded pipeline and
compare it with the recently proposed progressive growing of GANs.
