Abstract
En 中文
This paper deals with the creation of visual segment trees involved in MPEG-7 Description Schemes, After a brief overview of MPEG-7 Description Schemes in general and of the Segment Description Scheme in particular, tools allowing the creation of segment trees are discussed. The emphasis of the paper is on the creation of hierarchical relationship among segments, For this purpose, it is proposed to create a Binary Partition Tree in a first step and to restructure the tree in a second step. This approach is both efficient and flexible. Several examples involving spatial and temporal partition trees are presented. The proposed approach is appropriate to create both tables of contents and indexes. (C) 2001 Pattern Recognition Society. Published by Elsevier Science Ltd. All rights reserved.
