A new technique for labeling of components in document images is also proposed. A procedure for classifying retrieved images and a method of ranking the retrieved document images are also proposed. The retrieval results of the proposed TSR based indexing scheme is compared with nine-directional codes based (NDC) [2] indexing scheme and also with the retrieval results of human experts. The experiments are conducted on the MediaTeam document image database that provides diverse collection of document images.</ABSTRACT></RECORD></RECORDS></XML>
