Securing JPEG 2000 compressed images

Touradj Ebrahimi, Frédéric Dufaux

The Joint Photographic Experts Group (JPEG) has recently rolled out a new still image coding standard called JPEG 2000. This standard integrates an efficient image compression scheme along with functionalities required by multimedia applications, such as p ...

Secure JPEG 2000 - JPSEC

Touradj Ebrahimi, Raphaël Grosbois

The Joint Photographic Experts Group (JPEG) has recently rolled out a new still image coding standard called JPEG 2000. This standard integrates an efficient image compression scheme with functionalities required by multimedia applications, such as progres ...

Implementation of MPEG-4s Subdivision Surfaces Tools

This work is about the implementation of a MPEG-4 decoder for subdivision surfaces, which are powerful 3D paradigms allowing to compactly represent piecewise smooth surfaces. This study will take place in the framework of MPEG-4 AFX, the extension of the ...

Dynamic Region and Block-Based Motion Estimation for Video Compression

Pierre Vandergheynst, Philippe Jost

The aim of this project is to find a motion estimation method that works in combination with block matching in order to reduce the visible artifacts. The proposed solution tries to extract the real motions taking place in a sequence. The developed algorith ...

MPEG-7 Description of Generic Video Objects for Scene Reconstruction

Touradj Ebrahimi

We present an MPEG7 compliant description of generic video sequences aiming at their scalable transmission and reconstruction. The proposed method allows efficient and flexible video coding while keeping the advantages of textual descriptions in database ...

Lossy to lossless object-based coding of 3-D MRI data

Jean-Philippe Thiran, Gloria Menegaz

We propose a fully three-dimensional object-based coding system exploiting the diagnostic relevance of the different regions of the volumetric data for rate allocation. The data are first decorrelated via a 3D discrete wavelet transform. The implementation ...

Extension of Wavelet Compression Algorithms to 3D and 4D Image Data: Exploitation of Data Coherence in Higher Dimensions Allows Very High Compression Ratios

Michaël Unser

High resolution multidimensional image data yield huge datasets. For compression and analysis, 2D approaches are often used, neglecting the information coherence in higher dimensions, which can be exploited for improved compression. We designed a wavelet c ...

Smart Camera for MPEG-7

While a first generation of video coding techniques proposed to remove the redundancies in and between image frames to get smaller bitstreams, second generation schemes like MPEG-4 and MPEG-7 aim at doing content-based coding and interactivity. To reach th ...

JPEG2000: The upcoming still image compression standard

Touradj Ebrahimi

With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this need in the specific area of still image encoding, a new standard is currently being developed, the JPEG2000. It is n ...

AMISP: A Complete Content-Based MPEG-2 Error-Resilient Scheme

Pascal Frossard

We address a new error-resilient scheme for broadcast quality MPEG-2 video streams to be transmitted over lossy packet networks. A new scene-complexity adaptive mechanism, namely Adaptive MPEG-2 Information Structuring (AMIS) is introduced. AMIS modulates ...
