Eigen-Harmonics Faces: Face Recognition under Generic Lighting
The performances of face recognition systems are heavily subject to the variations in lighting. We propose a novel approach for face recognition under generic illumination conditi...

Rendering Iridescent Colors of Optical Disks
: Iridescent colors of optical disks are caused by light diffraction from their surface microstructure. This paper proposes a diffractive illumination model for optical disks based...

Estimating Lighting Direction and Classifying Textures
The appearance of a rough surface is affected by the direction from which it is lit and texture classifiers should account for this. We propose a classifier that is robust to ligh...

Real-time, all-frequency shadows in dynamic scenes
Shadow computation in dynamic scenes under complex illumination is a challenging problem. Methods based on precomputation provide accurate, real-time solutions, but are hard to ex...

Color Constancy Using Standard Deviation of Color Channels
We address here the problem of color constancy and propose a new method to achieve color constancy based on the statistics of images with color cast. Images with color cast have st...
