Color constancy based on the Grey-edge hypothesis
A well-known color constancy method is based on the GreyWorld assumption i.e. the average reflectance of surfaces in the world is achromatic. In this article we propose a new hypo...

Physics-based Edge Evaluation for Improved Color Constancy
Edge-based color constancy makes use of image derivatives to estimate the illuminant. However, different edge types exist in real-world images such as shadow, geometry, material...

Mechanism of Color Constancy
There are two widely held theories of color constancy based on very different mechanisms: Chromatic Adaptation and Spatial Comparisons. Chromatic Adaptation is based on the change...

Unified Crowd Segmentation
Abstract. This paper presents a unified approach to crowd segmentation. A global solution is generated using an Expectation Maximization framework. Initially, a head and shoulder d...
