A Differential Motion Estimation Method for Image Interpolation in Distributed Video Coding

Motion estimation methods based on differential techniques proved to be very useful in the context of video analysis, but have a limited employment in classical video compression because, though accurate, the dense motion vector field they produce requires ...

Image Interpolation with Dense Disparity Estimation in Multiview Distributed Video Coding

Thomas Maugey

This paper deals with the side information (SI) generation problem in multiview distributed video coding (MDVC). For inter-view interpolation, we propose a novel dense disparity estimation (DE) approach combined with a popular distributed video coding (DVC ...

Dense Disparity Estimation in a Multi-view Distributed Video Coding System

Thomas Maugey

Distributed video coding (DVC) is a recent paradigm which aims at transferring part of the coding complexity from the encoder to the decoder. The performance of such a coding scheme strongly depends on the capacity to estimate correlation at the decoder an ...

DISTRIBUTED VIDEO CODING: TRENDS AND PERSPECTIVES

Frédéric Dufaux, Wen Gao

This paper surveys recent trends and perspectives in distributed video coding. More specifically, issues such as coding efficiency, error resilience, multi-view coding, scalability, and applications beyond coding are overviewed. In addition, recent contrib ...

On Fidelity Per Unit Cost

Bixio Rimoldi, Marius Kleiner

We consider source coding with a ﬁdelity criterion, channel coding with a channel input constraint, and the combined problem of reproducing a source across a noisy channel. All three cases face a similar tradeoff between resource and performance, and the o ...

Towards a Comprehensive RVC VTL: A CAL Description of an Efficient AVC Baseline Encoder

Ihab Mostafa Amin Mohamed Amer, Karim Maarouf, Hussein Aman-Allah, Ehab Hanna

The Video Tool Library (VTL) is one of the major normative components of the Reconfigurable Video Coding (RVC) standard. It specifies the set of functional units (FUs)that may be interchangeably combined and connected to form different video codecs, with v ...

CAL Dataflow Components For an MPEG RVC AVC Baseline Encoder

Marco Mattavelli, Ihab Mostafa Amin Mohamed Amer, Karim Maarouf, Hussein Aman-Allah, Ehab Hanna

In this paper, an efficient H.264/AVC baseline encoder, described in RVC-CAL actor language, is introduced. The main aim of the paper is two folds: a) to demonstrate the flexibility and ease that is provided by RVC-CAL, which allows for efficient implement ...

Arithmetic Coding of Sub-Band Residuals in FDLP Speech/Audio Codec

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

A speech/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. The current version of the FDLP codec operating ...

Asymptotically Optimal Joint Source-Channel Coding with Minimal Delay

Bixio Rimoldi, Marius Kleiner

We present and analyze a joint source-channel coding strategy for the transmission of a Gaussian source across a Gaussian channel in n channel uses per source symbol. Among all such strategies, the scheme presented here has the following properties: i) the ...
