摘要: The problem of decomposing an extended boundary or contour into simple primitives is addressed with particular emphasis on Laplacian-of-Gaussian zero-crossing contours. A technique introduced for partitioning such contours constant curvature segments. nonlinear 'blip' filter matched to the impairment signature computation process, overlapped voting scheme, and a sequential contiguous segment extraction mechanism are used. This insensitive reasonable changes in algorithm parameters robust noise minor viewpoint-induced distortions shape, as those encountered between stereo image pairs. results vary smoothly data, local perturbations induce only result. Robustness insensitivity experimentally verified. >
