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 ...
2008Side-Information Scalable Source Coding
We consider the problem of side-information scalable (SI-scalable) source coding, where the encoder constructs a two-layer description, such that the receiver with high quality side information will be able to use only the first layer to reconstruct the so ...
Institute of Electrical and Electronics Engineers2008Bitstream format for spatio-temporal wave field coder
Martin Vetterli, Francisco Pereira Correia Pinto
We present a non-parametric method for compressing multichannel audio data for reproduction through Wave Field Synthesis. The method consists of applying a two-dimensional filterbank to the input mul- tichannel signal, in both time and channel dimensions, ...
2008Balanced Distributed Coding of Omnidirectional Images
Pascal Frossard, Ivana Tosic, Vijayaraghavan Thirumalai
This paper presents a distributed coding scheme for the representation of 3D scenes captured by a network of omnidirectional cameras. We consider a scenario where images captured at different viewpoints are encoded independently, with a balanced rate distr ...
2008Space-frequency quantization for image compression with directionlets
Martin Vetterli, Vladan Velisavljevic
The standard separable 2-D wavelet transform (WT) has recently achieved a great success in image processing because it provides a sparse representation of smooth images. However, it fails to efficiently capture 1-D discontinuities, like edges or contours. ...
2007Reconfigurable media coding: a new specification model for multimedia coders
Marco Mattavelli, Christophe Lucarz
Multimedia coding technology, after about 20 years of active research, has delivered a rich variety of different and complex coding algorithms. Selecting an appropriate subset of these algorithms would, in principle, enable a designer to produce the codec ...

IDIAP2007Adaptive Frame Interpolation for Wyner-Ziv Coding
This paper addresses the problem of frame interpolation for Wyner-Ziv video coding. A novel frame interpolation method based on block-adaptive matching algorithm for motion estimation is presented. This scheme enables block size adaptation to local activit ...
