Content-based image retrieval is an important application area for image processing methods associated with computer vision, pattern recognition, machine learning and other fields of artificial intelligence. Image content analysis enables us to use more natural, human-level concepts for querying large collections of images typically found in multimedia databases. Out of the numerous features proposed for image content description those based on frequency representation are of special interest as they often offer high levels of invariance to distortions and noise. In this chapter several frequency domain methods designed to describe different aspects of an image, i.e. contour, texture and shape are discussed. Current standards and database solutions supporting content-based image retrieval, including SQL Multimedia and Application Packages, Oracle 9i/10g interMedia and MPEG-7, are also presented.
