In the present work, an algorithm for ngerprints verication based on an application of the algebraic topology is presented. Specically, we propose a representation of impressions as simplicial complexes and the denition of local structures based on

In this paper, a topological approach for gait-based gender recognition is presented. First, a stack of human silhouettes, extracted by background subtraction and thresholding, were glued through their gravity centers, forming a 3D digital image I. S
