Mediatrix method for filamentation of objects in images

Clecio Roque De Bom, Martin Makler, Marcelo Portes de Portes de Albuquerque

Resumo


Nesta contribuição, nós descrevemos o método Mediatrix para filamentação de objetos. Este método é um processo iterativo que decompõe formas em filamentos seguindo a direção do maior brilho próximo ao eixo principal utilizando mediatrizes. A partir deste método é possível obter diversos atributos morfológicos como, por exemplo, o comprimento ao longo da direção principal, largura do objeto e, no caso de objetos curvos, é possível estimar o seu centro de curvatura e seu raio de curvatura. Como um exemplo ilustrativo, nós aplicamos esta técnica em objetos com forma de arco, obtidos através de simulações de arcos gravitacionais.
