We present a general framework for characterizing the object identity in a single image or a group of images with each image containing a transformed version of the object, with a...
An important class of color constant image descriptors is based on image derivatives. These derivative-based image descriptors have a major drawback: they are sensitive to changes...
This paper investigates the problem of object surface reflectance modeling, which is sometimes referred to as inverse reflectometry, for photorealistic rendering and effective m...
A simple and inexpensive approach for extracting the threedimensional shape of objects is presented. It is based on `weak structured lighting'; it di ers from other conventio...
Abstract. In this paper, we present novel image-derived, invariant features that accurately capture both the geometric and color properties of an imaged object. These features can ...
