Butterworth filter and Sobel edge detection to image

摘要

This paper discuss the detection Sobel edge dete ction prohibit of operator, The edge detection operator effect slove the problem of positioning, Uesing the high-pass Butter worth filter and Sobel edge detection operator, which effectivel y solve this problem. We use DSP programming environment to verify the feasibility of the method and experimental result s verify the proposed. this method is very effective.
