Estimation of 3D Shape of Warped Document Surface for Image Restoration
While scanning pages from a thick, bound book, there are two sources of distortion in the document images: 1) shade along the book `spine', and 2) warping of the book surface...

Shading Primitives: Finding Folds and Shallow Grooves
Diffuse interreflections cause effects that make current theories of shape from shading unsatisfactory. We show that distant radiating surfaces produce radiosity effects at low sp...

Shapelets Correlated with Surface Normals Produce Surfaces
This paper addresses the problem of deducing the surface shape of an object given just the surface normals. Many shape measurement algorithms such as shape from shading and shape ...

3D Surface Reconstruction by Self-Consistent Fusion of Shading and Shadow Features
In this paper a novel framework for three-dimensional surface reconstruction by self-consistent fusion of shading and shadow features is presented. Based on the analysis of at lea...

Warped Document Image Restoration Using Shape-from-Shading and Physically-Based Modeling
With the pervasive use of handheld digital devices such as camera phones and PDAs, people have started to capture images as a way of recording information. However, due to the non...
