The values and uncertain degrees of discrete fuzzy numbers

In this paper, we introduce the concepts of in-value, up-value, interval value and uncertain degree of discrete fuzzy numbers. These concepts are useful in the studding of some filter algorithms about digital images. Then, we discuss the properties of them and the values of discrete fuzzy numbers, obtain some results, and also give their calculation formulas, which are different with their definitions, and can more conveniently be used in material calculations.
