The Quality of Catadioptric Imaging ? Application to Omnidirectional Stereo
Abstract. We investigate the influence of the mirror shape on the imaging quality of catadioptric sensors. For axially symmetrical mirrors we calculate the locations of the virtual...

Estimation of the Size and Location of Multiple Area Light Sources
Most illuminant estimation algorithms worked on point light sources or directional light sources. Little attempt has been made, however, to estimate area light sources. In this pa...
