Title:
METHOD FOR CODING AND DECODING MULTIMEDIA DATA
Document Type and Number:
WIPO Patent Application WO2001041065
Kind Code:
A3
Abstract:
The invention relates to a method of coding a plurality of multimedia data according to which original multimedia data are acquired and converted into one or several bitstreams in which the different levels of information are then captured by means of analysis and segmentation. A description step allows to generate from said obtained levels of information description data that are then coded. More precisely, this description step comprises a defining sub-step, provided for storing a set of descriptors related to said plurality of multimedia data, and a description sub-step, provided for selecting the description data to be coded in accordance with every level of information as obtained in the structuring step. The set of descriptors includes, according to the invention, at least a shape descriptor and a shape deformation descriptor.
