Analysis of Confusion Matrix to Combine Evidence for Phoneme Recognition

Hynek Hermansky, Joel Praveen Pinto

In this work we analyze and combine evidences from different classifiers for phoneme recognition using information from the confusion matrices. Speech signals are processed to extract the Perceptual Linear Prediction (PLP) and Multi-RASTA (MRASTA) features ...

Artificial neural networks in spectrum fatigue life prediction of composite materials

Anastasios Vassilopoulos

An artificial neural network has been proved to be a sufficient tool for modelling fatigue life of multidirectional composite laminates made of GFRP composite materials and tested under constant amplitude loading patterns. Modelling efficiency of the netwo ...

A comparative study of JPEG 2000, AVC/H.264, and HD Photo

Touradj Ebrahimi, Francesca De Simone, Frédéric Dufaux, Mourad Ouaret

In this paper, we report a study evaluating rate-distortion performance between JPEG 2000, AVC/H.264 High 4:4:4 Intra and HD Photo. A set of ten high definition color images with different spatial resolutions has been used. Both the PSNR and the perceptual ...

On scalable source coding with decoder side informations

Suhas Diggavi

We consider the problem of scalable source coding with decoder side informations. Two special cases of this problem have been investigated in the literature, namely successive refinement Wyner-Ziv (SR-WZ) coding and side-information scalable (SI-Scalable) ...

On the significance of binning in a scaling-law sense

Michael Christoph Gastpar

An efficient distributed source coding system with two encoders and dependent data streams must remove two kinds of redundancy: redundancy in each stream and between the two streams. The striking result of Slepian and Wolf showed that the latter can be eli ...

MP3D: Highly Scalable Video Coding Scheme Based on Matching Pursuit

Pascal Frossard, Pierre Vandergheynst, Adel Rahmoune

This paper describes a novel video coding scheme based on a three-dimensional Matching Pursuit algorithm. In addition to good compression performance at low bit rate, the proposed coder allows for flexible spatial, temporal and rate scalability thanks to i ...

Image security and processing in the JPEG 2000 compressed domain

Raphaël Grosbois

Digital images are becoming increasingly successful thanks to the development and the facilitated access to systems permitting their generation (i.e. camera, scanner, imaging software, etc). A digital image basically corresponds to a 2D discrete set of reg ...
