In this paper, a classification-free Word-Spotting system, appropriate for the retrieval of printed historical document images is proposed. The system skips many of the procedures of a common approach. It does not include segmentation, feature extraction or classification. Instead it treats the queries as compact shapes and uses image processing techniques in order to localize a query in the document images. Our system was tested on a historical document collection with many problems and a Google book, printed in 1675. Moreover, some comparative results are given for a traditional word spotting system.
