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...

Efficient NURBS Rendering using View-Dependent LOD and Normal Maps
Rendering large trimmed NURBS models with high quality at interactive frame rates is of great interest for industry, since nearly all their models are designed on the basis of thi...

Surfels: surface elements as rendering primitives
Surface elements (surfels) are a powerful paradigm to efficiently render complex geometric objects at interactive frame rates. Unlike classical surface discretizations, i.e., tri...

Graph Based Discriminative Learning for Robust and Efficient Object Tracking
Object tracking is viewed as a two-class 'one-versusrest' classification problem, in which the sample distribution of the target is approximately Gaussian while the back...
