Layout Based Information Retrieval from Document Images

This research is intended to develop a layout based retrieval system for document image databases consisting of three phases: 1. At first, intelligent layout analysis algorithm has been designed to extract the layouts the document images physically with their edges and rectangles. 2. Every physically identified layout has been converted into a tree intermediary representation for indexing and storage in layout databases. Later when a query image has been supplied, it retrieves the similar layout images from the layout databases. 3. Finally, a logical layout analysis scheme has been proposed to identify the meaning of the layouts involved in the document images.
