摘　　要：基于形状特征的检索技术是图像检索的研究热点之一,提出一种基于图像形状方向能量的检索方法——先对图像进行一些基本的处理:去噪、边缘获取、细化边缘、调整角度,然后根据图像8个方向的能量累积,归一化处理,得到八个方向的能量累积数据。最后简述了图像智能检索系统的设计,应用该智能检索系统,给出了一些图片的基于方向能量检索方法的检索效果。The retrieval technique based on shape feature is one of the hotspots in image retrieval research. This paper puts forward a retrieval method based on image shape and direction energy. This method has two steps： first, do some basic treatments of the image, including denoising, procuring and thinning the edges and adjusting the angles; second, according to the energy accumulation of the eight directions of the image, make unitary processing to get cumulative energy data. In the end, this paper briefly states the design of the image intelligent retrieval system, and through the application of this system offers some image retrieval effects based on direction energy retrieval.
