Boundary Detection Algorithm Based on Semi-Subcomplexes

Abstract

In this paper, the concept of semi-open subcomplexes in abstract cellular complex is introduced and some of their properties are investigated by describing the notions of semifrontier, semi-interior and semi-closure. An efficient algorithm for tracing the semi-frontier of an image is introduced and is implemented through MATLAB. Finally, the semi-frontier algorithm is compared with the boundary tracing algorithm [G. Sai Sundara Krishnan, 2012].
