Abstract: We propose a new image fuzzy classification method which based on the image relational de-gree.The correlation degree basis points are obtained in each category,and the mean and standarddeviationσof relational degree are calculated for each category.Then the correlation degree for eachimage and the mean difference of correlation degree for each categoryΔi are calculated.IfΔi≤2σ,theimage should“stay”in the class,otherwise,the image should be associated with a greater correlationdegree of the other two categories.Each image should have such inspection to achieve image re-divi-sion until the process is stable.Comparison results show that the quality of the quality of the imageclassification method has certain advantages.
