| Abstract(in English) | In order to improve the retrieval accuracy of document image databases, it is necessary not to test the relevance between a query and each page / document, but to test whether each page contains parts relevant to a query. In this report, we propose a method for the retrieval of relevant parts of document images. In our method, the relevance is defined based on the observation that parts of document images are relevant if they densely contain keywords in a query. The use of 2D density distributions of feature vectors enables us to represent the density of keywords as well as to locate relevant regions in document images. |
