Lines 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
