| Abstract: | In B ultrasound image,there are a lot of noise,which causes many problem in edge detection.This article gives a edge detection method based on GVF snake model which is corrected by phase preserving denoising.This method can do good to our perception of images,remove or weaken false edge and make the detection more accurate. |
