Digital Bas-Relief Design: a Novel Shape from Shading-Based Method
Design of products characterized by high stylistic content and organic shapes in the form of bas-relief (e.g. fashion accessories, commemorative plaques and coins) is traditionally performed starting from handmade drawings or photographs that are manually reproduced by highly skilled craftsmen such as sculptors and engravers and finally digitized by means of 3D scanning. Several Computer-based ...
متن کاملBas-Relief Ambiguity Reduction in Shape from Shadowgrams
Coplanar shadowgrams provide an affordable mean to retrieve the 3d shape of an object especially when classical stereopsis fails (eg:textureless objects). Its principles are similar to the concepts used for Shape-From-Silhouettes with the only exception that here, light sources and cameras are interchanged. However, it is well known that any attempt to use the shadowgram to retrieve light sourc...
متن کاملRegion-based bas-relief generation from a single image
Bas-relief is an art form part way between sculpture and drawing. In this paper, we present an algorithm for generating a bas-relief from a single image, inspired by the process that artists use to create reliefs. We do not aim to recover exact depth values for objects in the image, which is a tricky computer vision problem, requiring assumptions that are rarely satisfied. Instead, we determine...
متن کاملKnowledge-Based Shape-From Shading
In this paper, we study the problem of recovering the approximate threedimensional shape of an object when knowledge about the object is available. The application of knowledge-based methods to image processing tasks will help overcome problems which arise from processing images using a pixel-based approach. We show that by applying domain specific knowledge, we can fully automate the derivatio...
متن کاملA Multigrid Method for Shape from Shading 1
The shape-from-shading problem has received much attention in the Computer Vision literature in recent years. The basic problem is to recover the shape z(x; y) of a surface from a given map of its shading, i.e. its variation of brightness over a given domain. Mathematically, one has to solve approximately the image irradiance equation R(p; q)(x; y) = E(x; y) relating a given image irradiance E(...
