On Neutrosophic Crisp Sets and Neutrosophic Crisp Mathematical Morphology

In this paper, we analyze the basic algebraic operations of neutrosophic crisp sets and their properties, show that some operations of neutrosophic crisp sets with type 2 and type 3 are not closed by counter examples, and give some new operations. Then, discuss some morphological operators in neutrosophic crisp mathematical morphology, and study the application to edge extraction of color images, and give some Python programs and related experimental results.
