Flow Direction Scalar Field and Fast Scanning Method Based Image Segmentation
基于流向标量场与快速扫掠法的图像分割

A fast automatic image segmentation method is presented through the combination of gradient vector flow (GVF) field and seeded region growing (SRG).First,a flow di- rection scalar (FDS) field is derived from GVF.Then,a new SRG method called fast scanning method (FSM) is proposed. Finally,region adjacency graph (RAG) based region merging is used to get the final result.This method is very efficient that it is possible to fit real-time applications if a fast GVF computation method is adopted.Experiments demonstrate its effectiveness and robustness.
