This work aims to present an introduction to Afim and Projective Geometries and their main resources through groups of transformations. Thus, it defines its properties, presents the theorems and the results of each geometry. ...

In this work, studies of two-dimensional transient heat diffusion problems in domains of rectangular and elliptical geometries, submitted to boundary conditions of first kind, were carried out. For the problem formulation, ...

The distance transform (DT) is a general operator forming the basis of many methods in computer vision and geometry, with great potential for practical applications. However, all the optimal algorithms for the computation ...
