The number of fuzzy subset can be confirmed by means of confirming number of best clustering in which the valid function of clustering is used 模糊子集個數(shù)的確定可以采用最佳聚類數(shù)的方法,即通過聚類有效性函數(shù)進行。
In order to decide the number of regions adaptively , this paper introduced a valid function based on intra - class and inter - class variance 同時為了自適應確定紋理分割區(qū)域數(shù),引入了一種基于類內(nèi)方差和類間方差的有效值函數(shù)。
