Relighting Acquired Models of Outdoor Scenes
In this paper we introduce a relighting algorithm for diffuse outdoor scenes that enables us to create geometrically correct and illumination consistent models from a series of ra...

Restoring 2D Content from Distorted Documents
—This paper presents a framework to restore the 2D content printed on documents in the presence of geometric distortion and nonuniform illumination. Compared with text-based docu...

Color Constancy with Spatio-Spectral Statistics
—We introduce an efficient maximum likelihood approach for one part of the color constancy problem: removing from an image the color cast caused by the spectral distribution of ...

On the Set of Images Modulo Viewpoint and Contrast Changes
We consider regions of images that exhibit smooth statistics, and pose the question of characterizing the “essence” of these regions that matters for visual recognition. Ideal...

Removing Shadows from a Single Real-World Color Image
In this paper, we propose a new algorithm to remove shadow from a single color image. We first project log-log chromaticity coordinates onto an angle of illumination-invariant dire...
