A Linearization–Based Hybrid Approach for 3D Reconstruction of Objects in a Single Image
International Journal of Applied Mathematics and Computer Science (IJAMCS), Volume 31, Issue 3Pages 501–513https://doi.org/10.34768/amcs-2021-0034AbstractThe shape-from-shading (SFS) technique uses the pattern of shading in images in order to obtain 3D view information. By virtue of their ease of implementation, linearization-based SFS algorithms are frequently used in the literature. In this study,...

Monocular 3D Reconstruction of Locally Textured Surfaces
IEEE Transactions on Pattern Analysis and Machine Intelligence (ITPM), Volume 34, Issue 6Pages 1118–1130https://doi.org/10.1109/TPAMI.2011.196Most recent approaches to monocular nonrigid 3D shape recovery rely on exploiting point correspondences and work best when the whole surface is well textured. The alternative is to rely on either contours or shading information, which has only been ...

Asymmetric facial shape based on symmetry assumption
It has been known that it is hard to capture the high-frequency components (shadows and specularities) during the modeling of illumination effects. In this paper, we propose a reflectance model to simulate the interaction of light and the facial surface ...

Shape from specular flow: Is one flow enough?
CVPR '11: Proceedings of the 2011 IEEE Conference on Computer Vision and Pattern RecognitionPages 2561–2568https://doi.org/10.1109/CVPR.2011.5995662Specular flow is the motion field induced on the image plane by the movement of points reflected by a curved, mirror-like surface. This flow provides information about surface shape, and when the camera and surface move as a fixed pair, shape can be ...
