Direct Computation of Shape from Shading
نویسندگان
چکیده
A direct method for the recovery of su$ace shape from image shading is presented. The method in its basic form is applicable to shading pattems obtained when a distant overhead point light-source illuminates a convex or concave Lambertian surface possessing a single extrema1 point at which surface height has either a local maximum or local minimum. A key quality of the method is its ability to operate without explicit prerequisite information conceming the shape of the sought-after surface. Consideration is also given to the manipulation of images of more complex surface shapes.

Can the Sun’s Direction Be Estimated Prior to the Determination of Shape? Wojciech Chojnacki
A smooth object depicted in a photographwill often exhibit brightness variation, or shading. Various computational techniques have been developed that perform reasonably well in inferring shape from shading. However, these techniques typically require substantial prerequisite information if they are to evolve an estimate of surface shape. It is therefore interesting to consider how depth might ...
متن کاملIllumination-Insensitive Face Recognition Using Symmetric Shape-from-Shading
Sensitivity to variations in illumination is a fundamental and challenging problem in face recognition. In this paper, we describe a new method based on symmetric shape-from-shading (SSFS) to develop a face recognition system that is robust to changes in illumination. The basic idea of this approach is to use the SSFS algorithm as a tool to obtain a prototype image which is illumination-normali...

متن کاملComputing 3D models of rotating objects from moving shading
This work reconstructs 3D graphics model of an object from an image sequence taken during the object rotation. Shading and its motion information are used in estimating shapes of smooth surfaces between fixed edges from corners and patterns. Being different from conventional shape from shadings that use one or several images, we use an image sequence that provides not only shading but also its ...
متن کاملThe direct computation of height from shading
We present a method of recovering shape from shading that solves directly for the surface height. By using a discrete formulation of the problem, we are able to achieve good convergence behavior by employing numerical solution techniques more powerful than gradient descent methods derived from variational calculus. Because we directly solve for height, we avoid the problem of nding an integrabl...
