Morphism Properties of Digital Categories

In this paper we defined the   category and researched the properties of monomorphism, epimorphism and isomorphism for digital categories which are related with the categorical structure in [1]. Also initial and terminal objects in digital categories are defined by using   adjacency relation. Hence we determined the initial and terminal objects of digital categories which have digital image with   adjacency as objects.    In addition to this we proved that the objects of the same type in a digital category are isomorphic.
