Département Artemis

Since 1998, ARTEMIS has been an active player in 3D graphics standardization by contributing to the MPEG-4 standard both at technical and managerial levels.

On the technical side, ARTEMIS has participated to Core Experiments on video compression, 3D mesh compression, and 3D graphics animation.

Since 1998, ARTEMIS has been involved in MPEG-4 standardization activities on 3D mesh coding by taking part to technical experiments both as an evaluator and a technology proponent. Since July 2006, ARTEMIS has been contributing to the experimental assessment process on animated 3D mesh compression by:

♦	creating a reference corpus for benchmarking candidate technologies on an objective comparative basis;
♦	initiating a new evaluation process;
♦	proposing 2 original technologies which are currently under evaluation.

Since 2001, ARTEMIS has innovated by proposing a complete framework for animating articulated structures such as virtual characters. This framework, today integrated in MPEG-4 Part 16 (ISO/IEC 14496-16) Animation Framework eXtension (AFX), consists of:

♦	the Skeleton, Muscle & Skin (SMS) content representation approach for simulating physical properties of 3D objects;
♦	the Bone-Based Animation (BBA) paradigm for representing motion parameters in a compact and compressed way;
♦	the MorphAnim technique for addressing high quality animation as the one required to realistically deal with faces.

For these various tools, ARTEMIS has provided Reference Software implementations and conformance bitstreams.

ARTEMIS involvement in managing 3D standardization activities refers to:

♦	chairing standardization groups, such as AFX Core Experiments & Exploration Experiments, AFX Profile and AFX Documents Editing;
♦	editing and maintaining the ISO/IEC 14496-16 standard.

This work was awarded with a Certificate of Appreciation by ISO/IEC in 2005.

The expertise on MPEG-4 3D accumulated by ARTEMIS throughout these years has been exploited in exploratory and pre-competitive projects such as the GET innovative project JEMTU, the national projects LABIAO, MICA and SEMANTIC-3D, and the European projects ViSiCAST, OLGA, Cream-3D, Jules Verne and Passepartout. In addition, an active dissemination strategy has been deployed in the form of scientific papers, tutorials and invited talks in international conferences.
