Distance-based Speed Functions for Level Set Methods in Image Segmentation

"Level set methods are a well-known means for the segmentation of objects in image data. In this paper, we discuss a class of easy to calculate terms based on distance measures for integration into the level set speed function. We will give examples for the use of these distance-based terms as a stopping criterion in the absence of reliable image features and as an acceleration force for the propagating front to connect parts of a single object. A comparison of the results with a level set segmentation not using any distance measures will be given to demonstrate the improvement of segmentation results."
