Figure 7. The image segmentation result with breast tissue applying the geodesic de-
formable model. The top left panel shows the initial curve, the top right and bottom left
panels show two snapshots of the evolving contours, and the bottom right panel shows the
final segmentation results after 8000 iterations. See attached CD for color version.
In addition to introducing the underlying logic and theory of deformable mod-
els, this chapter provides an overview of the requisite numerical techniques needed
to implement the algorithms and analyze imaged pathology specimens. A range
of different approaches were used to analyze identical image sets in order to il-
lustrate the comparative performance among each of the various strategies. The
segmentation results of actual imaged pathology specimens and stained tissue are
also provided for different approaches introduced in the chapter. We expect that
after reviewing this work, including the supporting mathematical background, that
readers will have sufficient understanding to implement these methods for practi-
cal imaging applications. Given the brevity of the chapter, it was necessary to omit
