Query: Towards Vivid and Diverse Image Colorization with Generative Color Prior   Colorization has attracted increasing interest in recent years. Classic
reference-based methods usually rely on external color images for plausible
results. A large image database or online search engine is inevitably required
for retrieving such exemplars. Recent deep-learning-based methods could
automatically colorize images at a low cost. However, unsatisfactory artifacts
and incoherent colors are always accompanied. In this work, we aim at
recovering vivid colors by leveraging the rich and diverse color priors
encapsulated in a pretrained Generative Adversarial Networks (GAN).
Specifically, we first "retrieve" matched features (similar to exemplars) via a
GAN encoder and then incorporate these features into the colorization process
with feature modulations. Thanks to the powerful generative color prior and
delicate designs, our method could produce vivid colors with a single forward
pass. Moreover, it is highly convenient to obtain diverse results by modifying
GAN latent codes. Our method also inherits the merit of interpretable controls
of GANs and could attain controllable and smooth transitions by walking through
GAN latent space. Extensive experiments and user studies demonstrate that our
method achieves superior performance than previous works.
