Multi-feature gradient vector flow snakes for adaptive segmentation of the ultrasound images of breast cancer
A new version of generalized gradient flow (GGVF) snakes involving multiple features of the vector field. Polynomial diffusion based on prescribed clusters of the edge map. A new, directional (orientation) feature integrated into the GGVF snake model. Preprocessing based on hierarchical clustering. A large series of numerical experiments with an in-depth analysis and tests against recent modifications of GGVF.
