Ultrasound imaging is a widely used and safe medical diagnostic technique, due to its non-invasive nature, low cost and capability of forming real time imaging. Ultrasound imaging uses high-frequency sound to image internal structures by differing reflection signals produced when a beam of sound is projected into the body and bounces back at interfaces(More)
Accurate and robust image segmentation is identified as one of the most challenging issues in Positron Emission Tomography (PET). The low spatial resolution, signal dependant noise levels and complex nature of anatomical structures have negative impact on qualitative and quantitative image segmentation analysis. Several unsupervised methods such as, Fuzzy(More)
