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...

Semidefinite Programming Heuristics for Surface Reconstruction Ambiguities
We consider the problem of reconstructing a smooth surface under constraints that have discrete ambiguities. These problems arise in areas such as shape from texture, shape from sh...

Retexturing Single Views Using Texture and Shading
We present a method for retexturing non-rigid objects from a single viewpoint. Without reconstructing 3D geometry, we create realistic video with shape cues at two scales. At a coa...

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...

Photometric and Geometric Restoration of Document Images Using Inpainting and Shape-from-Shading
The popularity of current hand-held digital imaging devices such as camera phones, PDAs, camcorders has promoted the use of digital cameras to capture document images for daily in...
