Abstract:
A modified Snake algorithm for medical image segmentation based on improved Greedy method and electrostatic field model is presented in this paper. Based on Greedy method, this algorithm features a new adjacent point selection strategy and the corresponding criteria, which can be used for searching the potential snake points. A new external image force based on electrostatic field model and the simplified force field computation based on preprocessing image are also introduced. Comparative experiments indicate the validity of the method.
