摘    要：介绍通过小波去噪,Sobel边缘检测算子提取边缘的方法,通过软件平台Labview实现,给出了各个步骤的演示图片。结果证明这种方法抗噪能力极强,提取的边缘定位精确,程序结构合理。

Abstract: The edge detection method through wavelet decomposition and Sobel operator edge detector is described,and it is implemented by Labview,and the demonstration image of every step is given.The experimental results show that the algorithm has a better immunity to the noise jamming of images and the edge position extracted by the algorithm is accurate,the structure of the procedure is rational.
