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.

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.

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.
