CBIR is retrieval of images based on some query or example images. It is also called Query based image retrieval. Firstly, this report outlines a descr iption of the primitive features of an image color and shape. These features are extracted and use

边缘是图像最基本的特征，包含图像中用于识别的有用信息，边缘检测是数字图像处理中基础而重要的内容。该课程设计具体考察了五种最常用的边缘检测算子并运用MATLAB进行图像处理比较。梯度算子简单有效，LOG算法和canny边缘检测器能产生较细的边缘。-边缘是图像最基本的特征，包含图像中用于识别的有用信息，边缘检测是数字图像处理中基础而重要的内容。该课程设计具体考察了五种最常用的边缘检测算子并运用MATLAB进行图像处理比较。梯度算子简单有效，LOG算法和canny边缘检测器能产生较细的边缘。边缘是图像
