Pixelated Semantic Colorization

Image Colorization

This project seeks to reproduce the work of [Levin] on colorization of a black and white image. The approach used takes two black and white images, which are identical except for color markings on one of them. The colored result is based on an optimization problem that has two sets of constraints: First, the color of pixels should be close to their marked color, if applicable. Second, the color...

Mesh Colorization

This paper proposes a novel algorithm for colorization of meshes. This is important for applications in which the model needs to be colored by just a handful of colors or when no relevant image exists for texturing the model. For instance, archaeologists argue that the great Roman or Greek statues were full of color in the days of their creation, and traces of the original colors can be found. ...

Automatic colorization of videos

Realistic colorization of videos has been of great interest to the artistic community, primarily for restoring historical color films and colorizing legacy videos. In this project, we experimented with several methods in order to automatically colorize videos on a frame-by-frame basis. We focused on rectifying two primary issues encountered with video colorizations : lack of color consistency b...

Image and Video Colorization

Multiple Hypothesis Colorization

In this work we focus on the problem of colorization for image compression. Since color information occupies a large proportion of the total storage size of an image, a method that can predict accurate color from its grayscale version can produce a dramatic reduction in image file size. But colorization for compression poses several challenges. First, while colorization for artistic purposes si...
