The study on content based multimedia data retrieval system

Abstract

Of late, advance in hardware and communications technology has been rapidly increasing the demand for diverse multimedia information, which, including all image, audio, video, text, numerical data, etc., should be designed to excel the existing information processing system in the functions of data storage, search, transmission, display, etc. The newest image retrieval system is gradually being converted from textbased into content-based retrieval, which uses the image content itself as features. In content-based retrieval, how to combine the color, shape, layout, texture, etc. used for describing each image or object is considered an important element. The existing method has chiefly used histogram out of the content-based image method using color information, but this has a drawback in being sensitive to brightness of light and the object size in the image. Thus, the present methods is intended to design and implement a system that can retrieve images similar to the query image from image database without losing image information in the use of color features. © 2011 Springer Science+Business Media, LLC.
