Paper Abstract

The cross-section topology is a framework that extends the notions of digital topology to the case of grayscale images. In this framework, the use of 4- and 8-connectedness induces geometric constraints in topological operators such as thinning operators. We propose a general method to obtain better results by reducing the anisotropy of such operators. We illustrate the method with an application to the segmentation of human head MRI images.
