Myth: An Accurate and Scalable Network Coordinate System under High Node Churn Rate
—Network coordinate (NC) system is an efficient mechanism to predict Internet distance (latency) with limited times of measurement. In this paper, we focus on the node churn pro...

Effects of Image Segmentation for Approximating Object Appearance Under Near Lighting
Shading analysis of an object under near lighting is not an easy task, because the direction and distance of the light source vary over the surface of the object. Observing a small...

Characterization of Human Faces under Illumination Variations Using Rank, Integrability, and Symmetry Constraints
Photometric stereo algorithms use a Lambertian reflectance model with a varying albedo field and involve the appearances of only one object. This paper extends photometric stereo a...
