Bi-level Feature Alignment for Versatile Image Translation and Manipulation. (arXiv:2107.03021v2 [cs.CV] UPDATED)

Generative adversarial networks (GANs) have achieved great success in image
translation and manipulation. However, high-fidelity image generation with
faithful style control remains a grand challenge in computer vision. This paper
presents a versatile image translation and manipulation framework that achieves
accurate semantic and style guidance in image generation by explicitly building
a correspondence. To handle the quadratic complexity incurred by building the
dense correspondences, we introduce a bi-level feature alignment strategy that
adopts a top-$k$ operation to rank block-wise features …
