This paper introduces a simple and efficient representation for natural images. We partition an image into blocks and treat the blocks as vectors in a high-dimensional space. We t...
Computer visualization has advanced dramatically over the last few years, partially driven by the exploding video game market. 3D hardware acceleration has reached the point where...
We develop a fast method to localize the level set method of Osher and Sethian (1988, Journal of Computational Physics) and address two important issues that are intrinsic to the l...

The educational content of a technical topic consists, ultimately, of elementary chunks of knowledge. Identifying and classifying such units -- Testable, Reusable Units of Cogniti...
Video-based target tracking is a challenging task, because there always appears to be complex occlusion among the varying number of objects. Also, in practice, it is very common t...
