conference on computer Vision and pattern recognition (CVPR)
作者: M. Styner G. Gerig Department of Computer Science University of North Carolina Chapel Hill NC USA
The paper presents a novel processing.scheme for the automatic computation of a medial shape model which is representative for an object population with shape variability. The sensitivity of medial descriptions to obj... 详细信息

conference on computer Vision and pattern recognition (CVPR)
作者: A.W. Fitzgibbon Department of Engineering Science University of Oxford Oxford UK
A problem in uncalibrated stereo reconstruction is that cameras which deviate from the pinhole model have to be pre-calibrated in order to correct for nonlinear lens distortion. If they are not, and point corresponden... 详细信息

NEURAL NETWORKS 2000年 第3期13卷 291-303页
作者: van Tonder, GJ Ejima, Y Kyoto Univ Lab Cognit Sci Grad Sch Human & Environm Studies Sakyou Ku Kyoto 6068501 Japan
We propose blind segmentation of images into shape-related 'patches' based on pre-calculated local symmetries (Van Tender, G.J. & Ejima, Y. (1999). (Forthcoming a) Flexible computation of shape symmetries.... 详细信息

ieee conference on computer Vision and pattern recognition, CVPR 2000
作者: Liang, Yufeng Simoncelli, Eero P. Lei, Zhibin Rutgers Univ Piscataway NJ United States
In this paper, we developed a color model to cancel the dependency between color channels, which enables us to separate spectral processing.from spatial processing. We introduced Independent Component Analysis (ICA) t... 详细信息

ieee conference on computer Vision and pattern recognition, CVPR 2000
作者: Geusebroek, Jan-Mark Smeulders, Arnold W.M. van den Boomgaard, Rein Univ of Amsterdam Amsterdam Netherlands
The measurement of object reflectance from color images is carried out. Illumination and geometrical invariant properties are derived from a physical reflectance model based on the Kubelka-Munk theory. Invariance, dis... 详细信息

作者: Zhang, Yufei Yang, Yee-Hong Univ of Saskatchewan Saskatoon Sask Canada
In this paper, a novel scheme of extracting multiple illuminant directions from an image of a Lambertian sphere of known size is proposed. The illuminant direction detection process is based on the concept of critical... 详细信息

ieee conference on computer Vision and pattern recognition, CVPR 2000
作者: Geusebroek, Jan-Mark Koelma, Dennis Smeulders, Arnold W.M. Gevers, Theo Univ of Amsterdam Amsterdam Netherlands
We will demonstrate our CVPR2000 paper 'Measurement of Color Invariants' for the cases of image retrieval based on query by example and for color image segmentation. Both are of importance in content based acc... 详细信息

ieee Workshop on Omnidirectional Vision (OMNIVIS 2000)
作者: Hicks, RA Bajcsy, R Drexel Univ Dept Math & Comp Sci Philadelphia PA 19104 USA
We present two families of reflective surfaces that are capable of providing a wide field of view, and yet still approximate a perspective projection to a high degree. These surfaces are derived by considering a plane... 详细信息

ieee conference on computer Vision and pattern recognition, CVPR 2000
作者: Vasconcelos, Nuno Lippman, Andrew MIT Media Lab United States
The design of an effective architecture for content-based retrieval from visual libraries requires careful consideration of the interplay between feature selection, feature representation, and similarity metric. We pr... 详细信息
