A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...

Abstract: In this paper, we propose a novel framework of analyzing the internal micro-structure of steel materials. Our framework consists of destructive imaging and geometric computing techniques.

Abstract: Shape from focus (SFF) reconstructs 3D shape of the scene from a sequence of multi-focus images, and the quality of reconstructed shape mainly depends on the accuracy of image focus volume ...
