User-Assisted Image Compositing for Photographic Lighting

A new approach that assists photographers to compose images of static scenes, viewed under dynamic lighting. The approach introduces a set of basis lights that combine several of the input images and provides controls to achieve effects photographers typically need; for example, accentuating the color or edges of objects.

Probabilistic Color-by-Numbers: Suggesting Pattern Colorizations Using Factor Graphs

A probabilistic factor graph model for automatically coloring patterns. The model is trained on example patterns and can be sampled to generate diverse colorings for a target pattern. Results are demonstrated on a variety of coloring tasks. In a study, participants preferred sampled colorings to other automatic baselines.

Optimizing Color Consistency in Photo Collections

A new method for automatically ensuring color consistency in typical real-world personal photo albums. Consistency may be induced without any user input, and user-specified edits of one or more photographs are automatically propagated to other photographs that share the same content.

Example-Based Video Color Grading

Color palettes of production movies are often adjusted by skilled colorists through a color-grading process that is difficult for amateurs to reproduce. This paper addresses this problem with an an example-based method. It solves temporal inconsistencies with a novel differential-geometry-based scheme akin to curvature flow.
