We show that the natural algebraic structure of singular chains on a path-connected topological space determines isomorphism class fundamental group functorially. Moreover, we describe notion weak equivalence for relevant

We define a fundamental group for digital images. Namely, we construct functor from images to groups, which closely resembles the ordinary algebraic topology. Our construction differs in several basic ways previously established versions of setting. development gives prominent role subdivision show that our is preserved by subdivision.
