Chapter 3 mainly discusses the theory of spatial autocorrelation.

第三章主要论述空间自相关度量理论。

To represent the shape content of an image, the edge orientation autocorrelogram is used. To represent color features, local color cumulative histogram is computed, and to solve the problem of lacking the spatial knowledge of the histograms, we also extract the color moments of the partitions.

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.

为了弥补全局颜色直方图不包含颜色空间分布关系,在La6颜色空间提取分块的颜色矩,同时利用边缘方向自相关图获得图像的形状内容,然后分别计算各特征的距离并利用Guassian模型进行特征归一化,综合上述各归一化距离,进行全局相似度量,最后采用了权值调整的相关反馈方法进一步提高检索精度。
