The state of the art in contemporary visual object categorization and classification is dominated by "Bag Of Words" approaches. These use either discriminative or generative learning models to learn the object or scene model. In this paper, we propose a novel "Bag of words" approach for content based image retrieval. Images are converted to virtual text documents and a new relevance feedback algorithm is applied on these documents. We explain how our approach is fundamentally different to

This merges the best of generative and discriminative approaches to achieve a robust and discriminative visual words based description of a visual concept. Our learning model and "Bag Of Words" approach achieve a balance between good classification and efficient image retrieval.
