Subjective evaluation of JPEG XR image compression

Touradj Ebrahimi, Francesca De Simone, Lutz Goldmann

In this paper a procedure for subjective evaluation of the new JPEG XR codec for compression of still pictures is described in details. The new algorithm has been compared to the existing JPEG and JPEG 2000 standards when considering compression of high re ...

Selected topics on distributed video coding

Mourad Ouaret

Distributed Video Coding (DVC) is a new paradigm for video compression based on the information theoretical results of Slepian and Wolf (SW), and Wyner and Ziv (WZ). While conventional coding has a rigid complexity allocation as most of the complex tasks a ...

On Comparing Image and Video Compression Algorithms

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

In this work, a performance evaluation of AVC Intra and JPEG2000 in terms of rate-distortion performance is conducted. A set of High Definition sequences with different spatial resolutions is used for this purpose. Results obtained show quite competitive p ...

Space-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. ...

JPEG2000 image coding system theory and applications

Touradj Ebrahimi

JPEG2000, the new standard for still image coding, provides a new framework and an integrated toolbox to better address increasing needs for compression. It offers a wide range of functionalities such as lossless and lossy coding, embedded lossy to lossles ...

Optimized Transmission of JPEG2000 Streams Over Wireless Channels

Nikolaos Thomos

The transmission of JPEG2000 images over wireless channels is examined using reorganization of the compressed images into error-resilient, product-coded streams. The product-code consists of Turbo-codes and Reed-Solomon codes which are optimized using an i ...

Coarse-to-fine textures retrieval in the JPEG 2000 compressed domain for fast browsing of large image databases

Pierre Vandergheynst, Christophe De Vleeschouwer, Benoît Macq

In many applications, the amount and resolution of digi- tal images have significantly increased over the past few years. For this reason, there is a growing interest for techniques allowing to efficiently browse and seek information inside such huge data ...

Region-Based Transform-Domain Video Scrambling

Touradj Ebrahimi

In this paper, we address the problem of scrambling regions of interest in a video sequence. We target applications such as video surveillance preserving privacy, anonymous video communications, or TV news safeguarding the anonymity of a source. We propose ...

Toward a secure JPEG

Touradj Ebrahimi, Frédéric Dufaux

In this paper, we propose a Secure JPEG, an open and flexible standardized framework to secure JPEG images. Its goal is to allow the efficient integration and use of security tools enabling a variety of security services such as confidentiality, integrity ...
