We describe a novel framework for two-phase image segmentation, namely the Fuzzy Region Competition. The functional involved in several existing models related to the idea of Region Competition is extended by the introduction of a fuzzy membership function. The new problem is convex and the set of its global solutions turns out to be stable under t...

... Given anatomical constraints in this application, the required elevational aperture was limited to 16 mm to enable imaging between the ribs, and the designed azimuthal aperture (~40 mm) was chosen to facilitate treatment of shallow targets while still achieving high in-plane azimuth resolution imaging. This results in an open beamforming architecture 2D array with an aperture similar to the Philips X6-1 [54,55] while avoiding the limitations of a fixed-design, proprietary micro-beamformer and embedded multiplexors and pulsers on ASICs. Our Verasonics based 1024-channel ultrasound system directly drives a two-dimensional array, and we aimed at independently driving each element. ...
... A more recent extension of the aforementioned twophase approaches is proposed in [21], where the authors develop a multiphase image segmentation method based on fuzzy region competition [25,35]. They start from the general N -phase region competition functional, introduce fuzzy membership functions and replace the error term by the data fidelity of the Mumford-Shah and Chan-Vese model, respectively. ...
