A Fast System for Drop Cap Image Retrieval
نویسندگان
چکیده
This paper deals with the retrieval of document images especially applied to the digitized old books. In these old books our system allows the retrieval of graphical parts and especially the drop caps. The aim of our system is to process large image databases. For that purpose, we have developed a fast approach based on a Run Length Encoding (RLE) of images. We use this last one in a image comparison algorithm using two steps: centering of images then a distance computation. Our centering step allows to solve the shifting usually met between scanned images. We present experiments and results of our system according to recognition abilities and processing times.
