Complex Wavelet Bases, Steerability, and the Marr-Like Pyramid

Michaël Unser, Dimitri Nestor Alice Van De Ville

Our aim in this paper is to tighten the link between wavelets, some classical image-processing operators, and David Marr's theory of early vision. The cornerstone of our approach is a new complex wavelet basis that behaves like a smoothed version of the Gr ...

The pre-log of Gaussian broadcast with feedback can be two

Michael Christoph Gastpar

A generic intuition says that the pre-log, or multi-plexing gain, cannot be larger than the minimum of the number of transmit and receive dimensions. This suggests that for the scalar broadcast channel, the pre-log cannot exceed one. By contrast, in this n ...

Analysis of Error Propagation Due to Frame Losses in a Distributed Video Coding System

Thomas Maugey

In this paper, we propose a theoretical model for the error propagation phenomenon generated by a frame loss in a distributed video coding framework. Using rate-distortion functions, we analyze the impact of a frame loss on the average distortion of a grou ...

Thanks to geolocalized remote control : the sound will follow

Daniel Thalmann, Frédéric Vexo, Mathieu Hopmann

Dematerialized music and MP3 players offer to the user the possibility of carrying his musical content everywhere. However, at home, the music collection is generally not centralized, split between different rooms and audio supports (CDs, MP3s, etc). In th ...

Wide-Band Perceptual Audio Coding based on Frequency-Domain Linear Prediction

Petr Motlicek, Hynek Hermansky

In this paper we propose an extension of the very low bit-rate speech coding technique, exploiting predictability of the temporal evolution of spectral envelopes, for wide-band audio coding applications. Temporal envelopes in critically band-sized sub-band ...

Codec-Independent Scalable Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

In this paper, we introduce novel schemes for scalable Distributed Video Coding (DVC), dealing with temporal, spatial and quality scalabilities. More specifically, conventional coding is used to obtain a base layer. DVC is then applied to generate enhancem ...

Non-uniform QMF Decomposition for Wide-band Audio Coding based on Frequency Domain Linear Prediction

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

This paper presents a new technique for perfect reconstruction non-uniform QMF decomposition developed to increase efficiency of a generic wide-band audio coding system based on Frequency Domain Linear Prediction (FDLP). The base line FDLP codec, operating ...

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 ...
