COMPARATIVE EXPERIMENTAL ANALYSIS OF MATLAB-BASED EDGE DETECTION OPERATORS FOR POTATO DISEASE LEAF IMAGES

Image edge detection is an important topic in the field of image processing and pattern recognition, and has important applications in practice. In this paper, some commonly used image edge detection operators are theoretically analysed, and the advantages and disadvantages of these operators in edge detection and their scope of application are comparatively analysed through the MATLAB software to implement the edge detection of various operators on the image of potato diseased leaves.
