Este trabalho apresenta um método computacional que permite corrigir, nas imagens mamográficas, as variações das densidade causadas pelo efeito \"heel\". Essas variações prejudicam tanto a visualização quanto o processamento computacional de
We present a fast and reliable algorithm that gives precise location of breast tumours for a partial mastectomy. Our algorithm is fully implemented in the Surface Evolver, which is a general-purpose simulator of physical experiments. By starting from

O diagnóstico radiográfico é baseado na análise das diferenças das densidades ópticas (DO) do filme, que deveriam ser provocadas apenas pelas estruturas anatômicas do paciente. Entretanto, a intensidade do feixe de raios X não é uniforme dev
In this paper we introduce a computational modelling that reproduces the breast compression processes used to obtain the mammogram. The main result is a programme in which one can track the first steps of virtual mammography. On the one hand, our mod

Recent advances in Agricultural Engineering include image processing, robotics and geographic information systems (GIS). Some tasks are still accomplished manually, like drawing plantation lines that optimize productivity. Herewith we present an algo

We introduce a fully written programmed code with a supervised method for generating Steiner trees. Our choice of the programming language, and the use of well-known theorems from Geometry and Complex Analysis, allowed this method to be implemented w
