Specular reflections and interreflections produce strong highlights in brightness images. These highlights can cause vision algorithms, such as, segmentation, shape from shading, binocular stereo, and motion detection to produce erroneous results. We present an algorithm f o r separating the specu-lar and d i f i s e components of reflection from images.(More)
There is increasing interest in the recovery of generalized cylinders (GCs) with curved spines. However, existing formulations of such GCs, for example those based on the Frenet-Serret frame or the tube model, suuer serious drawbacks: discontinuities, a lack of expressive power, \narrowing" in the plane normal to the spine, non-intuitive twisting behavior,(More)
