Randomized algorithms for tracking distributed count, frequencies, and ranks
We show that randomization can lead to significant improvements for a few fundamental problems in distributed tracking. Our basis is the count-tracking problem, where there are k...

A Geometric Foundation of Colorimetry
The physical properties of color are usually described by their spectra, eigenvector expansions or low-dimensional descriptors such as RGB or CIE-Lab. In the first part of the pap...

ChameleonBall
We propose a novel ball-type input/output (I/O) device—the ChameleonBall—that allows users to interact with colors in the real world. The ChameleonBall mainly consists of mult...
