Fundamentals and Applications of Image Retrieval: An Overview
Abstract
Images play an important role in conveying information. With the rapid development of computer technology, the amount of digital imagery data is rapidly increasing. There is an inevitable need for efficient methods that can help in searching for and retrieving the visual information that a user is interested in. An ever flourishing retrieval technique is contentbased image retrieval (CBIR), where the visual cues found in the images are exploited for representing and retrieving the images. In this article we give an overview of the main concepts of CBIR. We concentrate mainly on the feature extraction stage as it is considered the core of the CBIR engines. Areas where the CBIR strategies are applicable are also reviewed.
