Abstract

A novel segmentation method using deformable models for medical image segmentation was developed. As deformable model, Topological Active Nets (TAN) were used, model which integrates features of region-based and boundary-based segmentation techniques. The model deformation through time is controlled by an Artificial Neural Network (ANN) that learns how to move the nodes of the model based on their energy surrounding. The ANN is applied to each of the nodes and in different temporal steps until the final segmentation is reached. The ANN training is obtained by simulated evolution, using Differential Evolution (DE) to automatically obtain the ANN that provides the emergent segmentation. The proposed methodology was adapted and tested in three different medical domains, that is, Computed Tomography (CT), Cone Beam Computed Tomography (CBCT) and eye fundus images to demonstrate the potential of the segmentation technique.
