4th International Conference Colour in Film

Our journey starts by recounting some of the experiences we obtained when restoring historic additive colour systems, such as Dufaycolor, by working in the YCoCg colour space with an ad hoc video codec rather than in the RGB colour space. The main part is devoted to multispectral scanning of moving images and a video codec to process the generated data. This allows us to work in a classic restoration suite, like Diamant, on the band level and even on the bit-plane level of each spectral band. Supervised, semi-supervised and unsupervised deep learning techniques open new horizons of film and video restoration. The final part will be the possibility for an entirely new video codec, which enhances the two mentioned, virtually allowing us to work with any moving image data.
