Image retrieval : a first step for a human centered approach1

1 This work is a part of the SCOPIE project founded by the federations ELESA and IMAG, and realized in collaboration with the LIS and the LPNC laboratory. Abstract Image indexing using content analysis is known as a difficult task, involving the vision research domain. Using these tools in the context of a retrieval system is generally frustrating for users, due to a lack of interfaces development, and to the difficulty for users to understand the low-level features managed by the system. We propose in this paper a general point of view for introducing a link between such systems and potential users. This includes image features based on visual perception models, a relevance feedback model, and a graphical interface to express the information need through user-system interactions.
