Exploring temporal coherence among light transport paths is very important to remove temporally perception-sensitive artifacts in animation rendering. Using the contribution of a light transport path to all frames in an ...

A system has been developed that automatically extracts the iris region from photographs, computes the iris color in CIE u 'v ' diagram color space, and corrects the color based on a standard calibration target. This system ...

Images captured by digital video cameras usually have lower spatial resolution than digital still cameras. This paper addresses the problem of combining images from digital still cameras and video cameras to generate a ...

A new approach for recognizing human faces is presented that uses video sequences of natural, uncontrolled head rotations to capture face motion and dynamic appearance characteristics. Unlike traditional methods for face ...

In this paper we present a new metric camera self-calibration algorithm that does not require the global minimization of an error function and can produce all legal solutions to the three-camera self-calibration problem ...

This paper describes the mathematical theory of screw-transform manifolds and their use in camera self calibration. When a camera with fixed internal parameters views a scene from two different locations, the physical t ...

We present a novel global illumination algorithm which distributes more image samples on regions with perceptually high variance. Our algorithm iterates on a population of pixel positions used to estimate the intensity ...
