PLATO for Information Mining in Satellite Imagery

Satellite images are numerous and weakly exploited: it is ur- gent to develop an ecient and fast indexing/retrieval sys- tem to easy their access. Content-Based Image Retrieval systems (CBIR) are known to provide an ecient frame- work. We thus propose to associate a CBIR approach with text-based queries to adapt to these big (12000◊12000 pix- els) and semantically rich images. The presented system relies on a multimedia data mining system called PLATO able to adapt to any kind of multimedia data. Moreover state-of-the-art relevance feedback strategy is introduced to provide interactive learning and auto annotation. The ex- perimental results show that the proposed approach greatly reduces the user's eort of interpreting satellite images.
