摘要: The authors present a quantitative analysis of the viewpoint consistency constraint (VCC), which is fundamental principle behind model-based methods for recognizing 3-D objects from 2-D data. It defines measure error (VCE), based on formal model image feature errors. Existing establishing correspondences using VCC are discussed. poor performance incremental demonstrated and attributed to failure ensure that global improves during search. A more reliable method, ascent, uses VCE explicitly as heuristic state-space search, presented. two algorithms compared in an experimental study. approach alternative illustrated, may be applied object recognition generally. >
