Abstract

The paper presents a framework for information retrieval in visual databases containing colour images. The concept of approximation-based keypoints is adapted to colour images; building and detection of such keypoints are explained in details. The issues of matching images are only briefly highlighted. Finally, the idea of higher-level keypoints is proposed.
