In this paper, we present a new framework for organizing image collections into structures that can be used for indexing, browsing, retrieval and summarization. Instead of using tree-based techniques which are not suitable for images, we develop a new solution that is specifically designed for image collections. We consider both low-level image content and high-level semantics in an attempt to alleviate the semantic gap encountered by many systems. The fact that our model is based on a probabilistic framework makes it possible to combine it in a natural way with probabilistic techniques developed recently for image retrieval. The structure our model generates is applied for four purposes. The first is to provide retrieval module with an index, which allows it to improve retrieval time and accuracy, while the second is to provide users with a hierarchical browsing catalog that allows them to navigate the image collection by subject. This represents an additional step towards facilitating human-computer interaction in the context of image retrieval and navigation. The third aim is to provide users with a summarization of the general content of each class in the collection, and the fourth is a retrieval mechanism. Related issues such as relevance feedback and feature selection are also addressed. The experiments at the end of the paper show that the proposed framework yields some significant improvements
