Recently I have been preoccupied developing an Euclidean distance transform (EDT) tool. Although ITK provides functions to do this; there is a need to be able to perturb the transformation parameters. A recent MICCAI 2005 paper on left atrium segmentation is my motivation for experimenting with this function. The authors of the paper have published an intuitive algorithm to segment the left atrium by cutting the blood pool at narrowings. The narrowings, I am hoping can be detected after performing the EDT. There is however a great deal of user-interactivity still required at this stage, for segmentation.
