摘要
对基于空间关系的图像检索方法进行了全面的论述,提出了图像对象空间关系的形式化描述,通过邻近和邻近距阵以及数学期望和均方差,给出了一种在图像进行投影变换和旋转变换中保持不变的图像相似匹配算法,并为图像数据库检索提供了有力的支持。
This paper discusses the research phases of the image retrieval methods based on spatial relationships.The paper present s formalization description of the image retrieval methods based on spatial relationships.Through with neighbor matrix、mathematical expectation and average difference,it presents a method to solve the problem of measuring similarity of image.This method is a similarity matching algorithm in which the image is invariant when caryying through projection transformation and rotation transformation,and provide a good retrieval method for image databases.
