Web-WISE: Compressed Image Retrieval over the Web

Web-WISE is a system designed to address the need for efficient content-based seeking and retrieval of images on the web. It supports searching by multi-features, including color and texture. Web-WISE contains three automatic components, which are 1): Internet Agent responsible for searching the Web to fetch images; 2): Analysis Agent, which extracts the color and texture features of color JPEG images directly from compressed domain and 3): Query Agent, which explores the image database using certain metrics and returns a set of images (thumbnails) visually similar to the query image. Due to its generic design, adding other features to the system will be very natural, including the ability to index and retrieve other types of visual information and retrieval based on edge and shape. This paper presents the theoretic and practical background of the system, the schemes of these three components and the performance of the system.
