3D Shape Reconstruction of Unfolded Book Surface from a Scanner Image -Shape from Shading with Interreflections under Proximal Light Source
In this paper, we propose an efficient and stable algorithm to recover the 3D shape of an unfolded curved book surface from the shading information of a scanner image. This shape from shading problem in a real world environment has a global and complicated interdependency among the shape, the depth and the albcdo distribution of the book surface. Hence, the ovcrall surface shape must be recover...

متن کاملRecovering Shape of Unfolded Books Surface from a Scanner Image Using Eigenspace Method
In this study, we address the problem of recovering the cross section shape of an unfolded book from the image of its surface taken by the image scanner. To attack this problem, we propose the practical method using the eigenspaces which are constructed by some shape and intensity profile da ta L: Light SOW of the book surface to reduce the data size. In this M: Mirmr C: Lens method, the book s...
متن کامل3D Reconstruction of Interreflection-affected Surface Concavities using Photometric Stereo
Image-based reconstruction of 3D shapes is inherently biased under the occurrence of interreflections, since the observed intensity at surface concavities consists of direct and global illumination components. This issue is commonly not considered in a Photometric Stereo (PS) framework. Under the usual assumption of only direct reflections, this corrupts the normal estimation process in concave...
متن کاملLight Source Dependence in Shape from Shading
We investigated shape constancy in human shape from shading under variations of illuminant direction using a local attitude probe in conjunction with a perturbation analysis. Stimuli were computer generated and depicted ellipsoids in a structured setting. Even with these simple shapes subjects settings were systematically biased in the illuminant direction and were consistent with a regression ...
