We study graphical modeling in the case of stringvalued random variables. Whereas a weighted finite-state transducer can model the probabilistic relationship between two strings, ...
We present a perception system, called Artisan, that semi-automatically builds 3-D models of a robot’s workspace. Range images are acquired with a scanning laser rangefinder an...

Recently, simulation of natural phenomena, such as water, smokes, fire, clouds, have been attempted in computer graphics. Clouds play an important role when generating images of o...
On sparse images, contiguous runs of identical symbols often occur in the same coding context. This paper proposes a model for efficiently encoding such runs in a twodimensional s...
Compound images contain a mixture of natural images, text, and graphics. They need special care in the use of compression because text and graphics cannot withstand the significan...
