Most of the current image retrieval systems use "one-shot" queries to a database to retrieve similar images. Typically a Knearest neighbor kind of algorithm is used, where weights measuring feature importance along each input dimension remain fixed (or manually tweaked by the user), in the computati

Abstract
In contentโbased image retrieval, relevance feedback is an interactive process, which builds a bridge to connect users with the search engine. It leads to much improved retrieval performance by updating the query and the similarity measure according to a user's preference; and recently techniques have matured to some extent. However, most previous relevance feedback approaches exploit shortโterm learning (intraquery learning) that is dealing with the current feedback session but ignoring historical data from other users, which potentially results in a great loss of useful information. Fortunately, by recording and collecting feedback knowledge from different users over a variety of query sessions, longโterm learning (interquery learning) can be implemented to further improve the performance of contentโbased image retrieval in terms of effectiveness and efficiency. For this reason, longโterm learning has an increasingly important role in multimedia information searching. No comprehensive survey of longโterm learning has been conducted to date. To this end, the article addresses this omission and offers suggestions for future work. ยฉ 2008 Wiley Periodicals, Inc. Int J Imaging Syst Technol, 18, 160โ169, 2008

We propose to combine short-term block-based fuzzy support vector machine (FSVM) learning and long-term dynamic semantic clustering (DSC) learning to bridge the semantic gap in content-based image retrieval. The short-term learning addresses the small sample problem by incorporating additional image
The purpose of content based image retrieval (CBIR) systems is to allow users to retrieve pictures from large image repositories. In a CBIR system, an image is usually represented as a set of low level descriptors from which a series of underlying similarity or distance functions are used to conveni
Content-based image retrieval heavily relies on the indexing structure. Current index structures, such as the R-tree, the SS-tree and the X-tree, have a large overlapping area among their nodes, especially at the high (parent) levels of the indexing tree. The overlapping area causes the search engin
Database search engines are generally used in a one-shot fashion in which a user provides query information to the system and, in return, the system provides a number of database instances to the user. A relevance feedback system allows the user to indicate to the system which of these instances are
