Rodrigues, J. M. F.du Buf, J. M. H.2009-02-132009-02-13200513th Portuguese Computer Graphics Meeting (13EPCG 2005). - Vila Real, 12-14 October 2005. - p. 179-184AUT: JRO00913; DUB00865;http://hdl.handle.net/10400.1/105Lines and edges provide important information for object categorization and recognition. In addition, one brightness model is based on a symbolic interpretation of the cortical multi-scale line/edge representation. In this paper we present an improved scheme for line/edge extraction from simple and complex cells and we illustrate the multi-scale representation. This representation can be used for visual reconstruction, but also for nonphotorealistic rendering. Together with keypoints and a new model of disparity estimation, a 3D wireframe representation of e.g. faces can be obtained in the future.application/pdfengVisual cortexLine and edge detectionMulti-scaleVisual reconstructionNon-photorealistic renderingjournal article
