On the distortion exponents of layered broadcast transmission in multi-relay cooperative networks
In this paper, we consider the transmission of a Gaussian source over a cooperative relay network, and analyze its end-to-end distortion at high signal-to-noise ratio, in terms of ...

Rate distortion and denoising of individual data using Kolmogorov complexity
We examine the structure of families of distortion balls from the perspective of Kolmogorov complexity. Special attention is paid to the canonical rate-distortion function of a so...

Psychoacoustically Constrained and Distortion Minimized Speech Enhancement
Abstract--This paper considers a psychoacoustically constrained and distortion minimized speech enhancement algorithm. Noise reduction, in general, leads to speech distortion, and ...

Distortion optimal transmission of multi-layered FGS video over wireless channels
Abstract-- We identify an analytical expression for the distortion of a scalable video bitstream containing a Base Layer (BL) and one or more Enhancement Layer (EL) bitstreams. Con...

Improved Models of Distortion Cost for Statistical Machine Translation
The distortion cost function used in Mosesstyle machine translation systems has two flaws. First, it does not estimate the future cost of known required moves, thus increasing sea...

New view synthesis for stereo cinema by hybrid disparity remapping
The 3-D shape perceived from viewing a stereoscopic movie depends on the viewing conditions, most notably on the screen size and distance, and depth and size distortions appear be...

Towards high-precision lens distortion correction
This paper points out and attempts to remedy a serious discrepancy in results obtained by global calibration methods: The re-projection error can be rendered very small by these m...

On Scaling Laws of Diversity Schemes in Decentralized Estimation
This paper is concerned with decentralized estimation of a Gaussian source using multiple sensors. We consider a diversity scheme where only the sensor with the best channel sends...
