Butterworth filter and Sobel edge detection to image
Zhong Zhang, Geng Zhao · 2011
This paper discuss the detection Sobel edge detection prohibit of operator ,The edge detection operator effect solve the problem of positioning. Using the high-pass Butter worth filter and Sobel edge detection operator, which effectively solve this problem. We use DSP programming environment to verify the feasibility of the method and experimental results verify the proposed this method is very effective.
