整数阶滤波的分数阶Sobel算子的边缘检测算法
Edge detection algorithm of fractional order sobel operator for integer order differential filtering
摘要
Abstract
In view of the problem that the traditional integer order differential image is blurred and affected by noise,the algorithm starts with the improvement of the traditional integer order differential Sobel operator.The fractional differen-tial Sobel operator is derived with the fractional differential theory.The algorithm is combined with edge detection method of Sobel operator.The integer order differential Sobel operator is used as a filter and convolution operation with fractional order differential Sobel operator.The algorithm improves integer order differential Sobel operator.Fractional differential Sobel operator by integer order differential filtering solves the problems of low accuracy and poor noise resistance of the traditional edge detection operators successfully.Theoretical research and experimental results show that the edge detec-tion operator is more precise and robust to image edge details,which is better than the commonly used integer order differ-ential edge detection operator and the algorithm has good edge detection effect.关键词
