A shape-based approach to the segmentation of medical imagery using level sets.

A shape-based approach to the segmentation of medical imagery using level sets.

We propose a shape-based approach to curve evolution for the segmentation of medical images containing known object types. In particular, motivated by the work of Leventon, Grimson, and Faugeras (2000), we derive a parametric model for an implicit representation of the segmenting curve by applying p...
