Awesome Software for Image Coloring

A curated list of awesome AI-powered image coloring frameworks, libraries and software. Inspired by josephmisiti/awesome-machine-learning. It's a good idea to explore the GitHub topic as well - Topic "Image colorization". In comparison to the awesome list MarkMoHR/Awesome-Image-Colorization (which focuses on research papers), I focus on practical open-source software.

Considerations

Most of the software runs in Python, and requires some kind of an AI frameworks (e.g. Tensorflow) - which means you may need a GPU with a configured CUDA toolkit to run it in a reasonable time.
