Module Description

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.

Usage

Once the Region Selector, the Target Preprocessing and the Bubble Maker modules have been run we can feed the bubble image and preprocessed volume to this module.

The parameters have the following meaning: Initial Label Image: The output of the Bubble Maker module. Feature Image: The output of the Target Preprocessing module. Propagation Weight: Relates to the amount of inflating force applied inside the surface (can be negative). Curvature Weight: Influences roundness of the resulting interface. Greater weight, greater roundness. Prevents leaking through narrow openings. Advection Weight: It weights the influence of the advection term, which behaves like a magnet attracting the interface towards edges. Number of Iterations: Indicates duration of the evolution. Output Label Image: Resulting segmentation. For further details on parameter interpretation and mathematical formalities address to Caselles et al. paper.
