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 ...

Video Coding with Motion-Compensated Lifted Wavelet Transforms

This article explores the efficiency of motion-compensated three-dimensional transform coding, a compression scheme that employs a motion-compensated transform for a group of pictures. We investigate this coding scheme experimentally and theoretically. The ...

Oligoquantization in low-rate lossy source coding

The theory of high rate lossy source coding is well developed both with respect to the practice of quantization and its fundamental rate distortion limits. But many modern compression systems for natural signals such as audio and images operate at lower ra ...

Joint motion estimation and segmentation for very low bit rate video coding

Touradj Ebrahimi

Motion estimation is a key issue in video coding. In very low bitrate applications, the amount of the side information for the motion field presents an important portion of the total bitrate. This paper presents a joint motion estimation, segmentation and ...

Rate constraints for video transmission over ATM networks based on joint source/network criteria

Martin Vetterli

In this paper, we study the rate constraints required for variable rate video transmission over ATM networks. Our objective is to achieve both good source quality and efficient network utilization. We show that these objectives may not be achieved simultan ...

Video coding using a pyramidal Gabor expansion

Touradj Ebrahimi, Murat Kunt

A compression technique based on an expansion is presented. The elementary functions of the expansion form a class of pyramidal Gabor functions covering the frequency domain in octave bands. The image sequence is coded by differentially coding selected coe ...
