Abstract: This paper describes an extraction method of shape feature of images based on edge direction histogram. The shape feature extracted is invariant to scale, translation and rotation. The experiment result illuminates that the method has a good retrieval performance for images that contain a single background and obvious shape.

Key words: edge direction histogram, edge detection, image shape, image retrieval
