Objective
The explosion of multimedia applications leads to a great expansion of video transmission over heterogeneous channels. These developments increase the need for highly flexible and scalable video compression systems. For all currently available interactive multimedia applications however, which are demanding in terms of video quality and coding efficiency, the cost as well as the limited scalability remain unacceptable. Therefore, MASCOT seeks to design an intrinsically scalable video-coding scheme providing fully progressive bit streams by exploiting novel morphological and adaptive wavelet decomposition methods. Furthermore, the project aims to improve the quality and efficiency of video coding systems by exploiting metadata information.

OBJECTIVES
1. To develop scalable compression schemes, which fulfil the requirements of multimedia applications, by covering a wide range of bit-rates, by yielding high compression ratios, and by providing a high level of bit stream embeddedness to enable the adaptation of the compressed video data to a variety of networks and receivers;
2. To provide a breakthrough in the domain of video compression and to improve the quality of the reconstructed video at low bit rates by exploiting non-linear (morphological, adaptive) wavelet decompositions, by using metadata during the encoding step, and by development and optimisation of advanced prediction schemes;
3. To provide Europe with a leadership in new video compression techniques;
4. To contribute to standardisation committees like ITU-T and MPEG, and to follow the activities of MPEG-7 (and MPEG-21) as well as JPEG-2000.
DESCRIPTION OF WORK
The work will consist of the following ingredients:
1. The analysis of the descriptors and description schemes included in the MPEG-7 standard or in other metadata standards such as SMPTE. Can such descriptors lead to the development of new coding techniques? Besides new tools that may be developed based on specific descriptors or description schemes, the access to metadata also opens the door to the design of new encoding strategies;
2. Investigation of new spatiotemporal decompositions for image and video coding and the development of new functionalities in the domain of video compression enabling user-friendly and flexible multimedia applications as well as the facilitation of the interoperation of heterogeneous systems. Towards this goal, new non-linear (morphological, adaptive) wavelet representations for video compression will be designed. Such wavelet representations will be exploited for special applications e.g. texture extraction, edge detection and motion estimation;
3. The investigation of various parameters to describe changes in time between pictures in order to capture the time redundancy inside a picture sequence and reduce the necessary amount of data to code. This investigation will cover the nature of the parameters to use as well as the choice of a picture representation on which they will act (space domain or wavelet domain). This will also include the choice of adaptive representations that enables us to take optimal advantage of this redundancy;
4. An encoder and decoder system will be developed according to the project's proposal. The focus of this codec will lie on scalable coding and on the usage of metadata (MPEG-7) to control the coding process. This new scheme will be compared with H.26L and MPEG-4 and a demonstration at a major international exhibition will be given.
