Information-Geometrical Significance of Sparsity in Gallager Codes
We report a result of perturbation analysis on decoding error of the belief propagation decoder for Gallager codes. The analysis is based on information geometry, and it shows tha...

Analysis of the efficiency of snr-scalable strategies for motion compensated video coders
In this paper, an analysis of the efficiency of three signal-to-noise ratio (SNR) scalable strategies for motion compensated video coders and their non-scalable counterpart is pre...

A symbolic approach to polyhedral scene analysis by parametric calotte propagation
Polyhedral scene analysis studies whether a 2D line drawing of a 3D polyhedron is realizable in the space, and if so, parameterizing the space of all possible realizations. For gen...
