An Indexing Method for Graphical Documents
Salvatore Tabbone, Daniel Zuwala · Proceedings of the International Conference on Document Analysis and Recognition · 2007
In this paper, a method to browse symbols into graphical documents is presented. More precisely, we propose a combined filtering and indexing mechanism that retrieves in an efficient way the most similar symbols to a given input query. For a database of 200000 symbols the retrieval time has been divided by a factor of 4, 5 compared to a linear search.
