Structure and Motion from Lines under Affine Projections
In this paper we investigate the geometry and algebra of multiple projections of lines with affine cameras. Previously, the case of seven lines in three images has been studied. I...

A suggestive interface for image guided 3D sketching
We present an image guided pen-based suggestive interface for sketching 3D wireframe models. Rather than starting from a blank canvas, existing 2D images of similar objects serve ...

Image-based rendering with occlusions via cubist images
We attack the problem of image-based rendering with occlusions and general camera motions by using distorted multiperspective images; such images provide multiple-viewpoint photom...

Recognition of Digital Images of the Human Face at Ultra Low Resolution Via Illumination Spaces
Recent work has established that digital images of a human face, collected under various illumination conditions, contain discriminatory information that can be used in classifica...

Recovering Local Shape of a Mirror Surface from Reflection of a Regular Grid
Abstract. We present a new technique to recover the shape of an unknown smooth specular surface from a single image. A calibrated camera faces a specular surface reflecting a calib...
