Shape from stereo: a systematic approach using quadratic surfaces.
We used quadratic shapes in several psychophysical shape-from-stereo tasks. The shapes were elegantly represented in a 2-D parameter space by the scale-independent shape index and the scale-dependent curvedness. Using random-dot stereograms to depict the surfaces, we found that the shape of hyperbolic surfaces is slightly more difficult to recognize than the shape of elliptic surfaces. We found...
متن کاملShape Reconstruction of Symmetric Surfaces Using Photometric Stereo
The reconstruction of a 3D surface through one gray scale digital image does not admit a unique solution in the orthographic Shape from Shading (SfS) framework. With the aim to make this type of problem well-posed it is possible to use the Photometric Stereo (PS) technique. It allows to add information about the surface introducing other images of the object taken from the same point of view bu...
متن کاملA Shape-From-Shading Algorithm Using Photometric Stereo
We present a simple shape-from-shading algorithm that uses two shading images. This enables us to estimate more accurate shapes of objects without any special constraints or conditions than the existing photometric stereo algorithms. The Jacobi’s iterative method is applied to the difference between the image and the reflectance function represented as a function of three depth parameters for e...
متن کاملCombining Shape from Shading and Stereo Using Human Vision Model Combining Shape from Shading and Stereo Using Human Vision Model
Stereo algorithms suuer from the lack of local surface texture due to smoothness of depth constraint , or local miss-matches in disparity estimates. Thus, the stereo methods only provide a coarse depth map which can be associated with a low pass image of the depth map. On the other hand, shape from shading algorithms produce better estimates of local surface areas, but some of them have problem...
متن کاملA New Shape from Shading Approach for Specular Surfaces
Shape recovery is a basic problem in computer vision. Shape from shading (SFS) is an approach to get the 3D shape from a single shading image. Diffuse model is usually used to approximate the surface reflectance property. For specular surfaces, however, it is not suitable. In this paper, we propose a new SFS approach for specular surfaces. The Blinn-Phong reflectance model is applied to charact...
