摘要： 描述了一种基于边缘方向直方图（Edge Direction Histogram，EDH）的图像形状特征提取方法，算法提取的特征向量同时满足尺度、平移和旋转不变性。实验证明该方法对于具有单一背景、形状特征明显的图像具有较好的检索效果。

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
