BigColor: Colorization using a Generative Color Prior for Natural Images

Graphic colorization is applied to modernize typical black-and-white movies or provide creative management in excess of grayscale imagery with diverse colour distributions. Even so, current solutions usually final result in desaturated and unnatural colors. A latest paper on arXiv.org proposes BigColor, a novel picture colorization approach that synthesizes vivid and all-natural hues for in-the-wild photos with intricate constructions.

Researchers exploit the spatial composition of an enter grayscale picture employing a convolutional encoder that permits enlarging the representation space of a generator in comparison to the common colorization.

BigColor can system photographs with arbitrary measurements, which have been not feasible for traditional approaches. Furthermore, multi-modal colorization results can be synthesized by using unique issue vectors for the network. Intensive experiments verify that BigColor outperforms past strategies.

For sensible and vivid colorization, generative priors have lately been exploited. Nonetheless, this sort of generative priors usually fall short for in-the-wild complicated images because of to their restricted representation space. In this paper, we propose BigColor, a novel colorization solution that offers vivid colorization for assorted in-the-wild illustrations or photos with complicated buildings. When former generative priors are educated to synthesize both of those image buildings and colours, we find out a generative colour prior to target on color synthesis presented the spatial composition of an picture. In this way, we minimize the burden of synthesizing graphic structures from the generative prior and broaden its representation space to include varied illustrations or photos. To this finish, we propose a BigGAN-encouraged encoder-generator community that works by using a spatial feature map in its place of a spatially-flattened BigGAN latent code, ensuing in an enlarged representation room. Our technique permits sturdy colorization for numerous inputs in a single forward move, supports arbitrary enter resolutions, and supplies multi-modal colorization final results. We display that BigColor appreciably outperforms present procedures specially on in-the-wild images with elaborate structures.
