Compression et accessibilité aux images de documents numérisés : application au projet DEBORA

Abstract : On-line digital libraries using documents images meet some technical problem like the lack of detailed metadata for fine queries, the space used by images which limit their transmission through the network and the missing of a file format suited for the navigation among heterogeneous data. In this framework, we propose methods for digitised documents contents understanding in order to improve image compression and to retrieve automatically useful metadata for documents indexing. Our approach is based on the partition of the images into independent objects that we compress with appropriate methods. We also propose a file format suited for the query and the consultation of compressed books which allow to edit , annotate and exchange data and metadata for a collaborative work.
