The most existing systems of CBIR fulfill the tasks of retrieving the similar images through computing the degree of similarity of different images. 当前，该研究领域所面临的主要困难在于，大多数现存的基于内容的图像检索系统是通过对不同图像进行相似度计算来完成图像检索任务的。
But, in the Similarity-Based fuzzy data model, the resemblance relation of redundant tuples has transitivity, and when merging the tuples, there is no previous problem. 而在相似型模糊资料模式中，值组间相似度所构成的关系具有递移性，故合并时不会发生前者的问题。
