用边缘方向自相关图表示图像的形状内容；对于颜色特征，计算图像颜色的局部累加直方图，同时为了弥补其不包含颜色空间分布关系的缺点，又提取了分块的颜色矩，并利用高斯模型对各特征距离进行归一化，综合上述三个归一化距离，进行全局相似度量。

The color moments of partitions are extracted from the L(superscript *)a(superscript *)b(superscript *) color space to solve the problem that the global color moment excludes the color space distribution, the edge orientation autocorrelogram is used to represent the shape content of an image, and the feature distance is respectively computed. The Guassian model is used to normalize the feature. Based on the normalized distance, the global similarity measure is obtained, and the retrieval precision is improved by the weight value adjustment.
