Abstract

For smooth curved surfaces the dominant image feature is the apparent contour or outline. This is the projection of the contour generator — the locus of points on the surface which separate visible and occluded parts. The contour generator is dependent of the local surface geometry and the viewpoint. Each viewpoint will generate a different contour generator. This paper addresses the problem of recovering the 3D shape and motion of curves and surfaces from image sequences of apparent contours.
