Some properties of the Euler characteristics for digital images are given. We also present reduced homology groups for digital images. The main purpose is to obtain some differences between notions in digital topology and algebraic topology. © 2014 NSP Natural Sciences Publishing Cor.en10.12785/amis/080529info:eu-repo/semantics/closedAccessDigital imageDigital relative homology groupEuler characteristicsArticle8523372345Q4
