Summary on Grant Application Form |
|
Evolving object-based video coding standards, such as MPEG-4, represent a significant departure from established frame-based standards (MPEG-1, MPEG-2, ITU-T H.261/263). Radically different functionalities are being introduced at the expense of increased computational complexity, and there exists a demand for even greater compression to incorporate the new functionalities and permit communications over widely available low bandwidth channels, for example in mobile multimedia communications. This proposal considers motions estimation, a process critical to the compression and quality of most video coding systems, and one which often provides the greatest computational demands., It is proposed to develop efficient motion estimation and shape coding techniques specifically designed for arbitrary-shaped video objets, and to maximise their effectiveness for low bandwidth communication systems. Consideration will be given to spatial and temporal scalability issues, the coding of multiple objects, and user interactivity. The implications of the coding method on the selective and prioritised coding of objects, content-based indexing, and future functionalities such as those proposed by MPEG-7, will also be considered.
