Intrinsic colorization
TLDR
In this paper, we present an example-based colorization technique robust to illumination differences between grayscale target and color reference images, and obtain the final result with excellent color consistency. Expand

Data-driven image color theme enhancement
TLDR
We formulate our goal as a unified optimization that simultaneously considers a desired color theme, texture-color relationships as well as automatic or user-specified color constraints. Expand
