This module is capable of evolving a label image according to a level-set customizable equation for a given number of iterations according to the preprocessed version of a given input image, thus segmenting that image. Ultimately it will be migrated to an interactive approach in which the level-set evolution can be controlled as it is being displayed, running step by step.
The level-set equation incorporates terms for propagation, curvature, and advection.
|The parameters have the following meaning:
The usage of this module implies a certain amount of trial and error, tuning parameters according to the incorrect segmentations obtained in the first runs. If you get leaking adjust curvature weight and propagation force or run for less iterations, according to what is happening in order regions(under-growth). A couple trials will provide the user with a feeling of the influence of the different parameters.
For further details on parameter interpretation and mathematical formalities address to Caselles et al. paper.
