Phase- and GVF-Based Level Set Segmentation of Ultrasonic Breast Tumors
Automatically extracting breast tumor boundaries in ultrasound images is a difficult task due to the speckle noise, the low image contrast, the variance in shapes, and the local changes of image intensity. In this paper, an improved edge-based active contour model in a variational level set formula...
