Luminance-chrominance model for image colorization

F Pierre, JF Aujol, A Bugeau, N Papadakis… - SIAM Journal on Imaging …, 2015 - SIAM
This paper provides a new method to colorize gray-scale images. While the computation of
the luminance channel is directly performed by a linear transformation, the colorization …
