International Conference on Computer Vision Workshops (ICCV Workshops)
作者: Michael Bleier Christian Riess Shida Beigpour Eva Eibenberger Elli Angelopoulou Tobias Tröger André Kaup Pattern Recognition Lab University of Erlangen-Nuremberg Germany Computer Vision Center Universidad Autónoma de Barcelona Spain Multimedia Communications and Signal Processing University of Erlangen-Nuremberg Germany
The color and distribution of illuminants can significantly alter the appearance of a scene. The goal of color constancy (CC) is to remove the color bias introduced by the illuminants. Most existing CC algorithms assu... 详细信息

International Conference on pattern recognition
作者: Serhat Selcuk Bucak Bilge Gunsel Electrical-Electronics Eng. Faculty Department of Electronics and Communications EngineeringMultimedia Signal Processing and Pattern Recognition Laboratory Istanbul Technical University Istanbul Turkey
Nonnegative matrix factorization (NMF) has been shown to be an efficient clustering tool. However, NMF¿s batch nature necessitates recomputation of whole basis set for new samples. Although NMF is a powerful cont... 详细信息
