The final contribution of this thesis is the development of an active contour model that offers a tractable implementation of the original Mumford-Shah model to simultaneously segment and smoothly reconstruct the data within a given image in a coupled manner. By generalizing the Mumford-Shah model, we are able to apply this active contour model to problems in which data quality varies between different locations in the image and, in the limiting case, to images in which pixel measurements are missing. We then modify this active contour model to obtain a novel PDE-based approach to image magnification, yielding a new application of the Mumford-Shah paradigm. Finally, we demonstrate the utility of this thesis by applying one of the image processing methodologies that we developed to a medical application, specifically, MR guided prostate brachytherapy.
