A General System for the Retrieval of Document Images from Digital Libraries

Large collections of scanned documents (books and journals) are now available in Digital Libraries. The most common method for retrieving relevant information from these collections is image browsing, but this approach is not feasible for books with more than a few dozen pages. The recognition of printed text can be made on the images by OCR systems, and in this case a retrieval by textual content can be performed. However, the results heavily depend on the quality of original documents. More sophisticated navigation can be performed when an electronic table of contents of the book is available with links to the corresponding pages. An opposite approach relies on the reduction of the amount of symbolic information to be extracted at the storage time. This approach is taken into account by document image retrieval systems. In this paper we describe a system that we developed in order to retrieve information from digitized books and journals belonging to Digital Libraries. The main feat...
