Noise-Resilient Group Testing: Limitations and Constructions

We study combinatorial group testing schemes for learning

d

-sparse boolean vectors using highly unreliable disjunctive measurements. We consider an adversarial noise model that only limits the number of false observations, and show that any noise-resilie ...

Speech/Non-Speech Detection in Meetings from Automatically Extracted Low Resolution Visual Features

Silèye Oumar Ba

In this paper we address the problem of estimating who is speaking from automatically extracted low resolution visual cues from group meetings. Traditionally, the task of speech/non-speech detection or speaker diarization tries to find who speaks and when ...

On Evaluating Video Object Segmentation Quality: A Perceptually Driven Objective Metric

Touradj Ebrahimi, Elisa Drelie Gelasca

The task of extracting objects in video sequences emerges in many applications such as object-based video coding (e.g., MPEG-4) and content-based video indexing and retrieval (e.g., MPEG-7). The MPEG-4 standard provides specifications for the coding of vid ...

Coding of spatio-temporal audio spectra using tree-structured directional filterbanks

Martin Vetterli, Francisco Pereira Correia Pinto

We address the problem of integrating directional analysis of sound into the filterbank of a spatial audio coder, with the purpose of processing and coding with some degree of inde- pendence the plane waves traveling in different directions. A plane wave r ...

Performance Analysis of a Hybrid Incremental and Cyclic A/D Conversion Principle

Pierre-André Farine, Luca Rossi, Steve Tanner

This paper presents a new hybrid A/D conversion principle based on the combination of an incremental conversion for the most significant part of the result and on a cyclic conversion for the least significant part. The proposed approach exhibits a resoluti ...

Spectral Noise Shaping: Improvements in Speech/Audio Codec Based on Linear Prediction in Spectral Domain

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Audio coding based on Frequency Domain Linear Prediction (FDLP) uses auto-regressive models to approximate Hilbert envelopes in frequency sub-bands. Although the basic technique achieves good coding efficiency, there is a need to improve the reconstructed ...

Temporal Masking for Bit-rate Reduction in Audio Codec Based on Frequency Domain Linear Prediction

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Audio coding based on Frequency Domain Linear Prediction (FDLP) uses auto-regressive model to approximate Hilbert envelopes in frequency sub-bands for relatively long temporal segments. Although the basic technique achieves good quality of the reconstructe ...

Entropy coding of Quantized Spectral Components in FDLP audio codec

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Audio codec based on Frequency Domain Linear Prediction (FDLP) exploits auto-regressive modeling to approximate instantaneous energy in critical frequency sub-bands of relatively long input segments. Current version of the FDLP codec operating at 66 kbps h ...

Balanced multiple description coding in image communications

Ivana Radulovic

Latest developments in video coding technology on one side, and a continuous growth in size and bandwidth in lossy networks on the other side, have undoubtedly created a whole new world of multimedia communications. However, nowadays networks, which are be ...
