This model runs on Nvidia A40 (Large) GPU hardware. Predictions typically complete within 4 seconds. The predict time for this model varies significantly based on the inputs.


🎨 DDColor

Implementation of ICCV 2023 Paper “DDColor: Towards Photo-Realistic Image Colorization via Dual Decoders”.

🪄 DDColor can provide vivid and natural colorization for historical black and white old photos.

🎲 It can even colorize/recolor landscapes from anime games, transforming your animated scenery into a realistic real-life style! (Image source: Genshin Impact)


In short: DDColor uses multi-scale visual features to optimize learnable color tokens (i.e. color queries) and achieves state-of-the-art performance on automatic image colorization.
