Abstract：Aiming at the defect that the traditional Canny operator edge detection easily lost the edge de-tails,an improved technology was developed to extract the edges of the leaf disease region.More complete gradient information was preserved by using Otsu to binary plant disease images and adding on two oblique directions gradient information extraction,so as to get a more complete edge image.The experimental re-sults showed that this method could effectively filter out noise in the image and detect the details of the gra-dient,remove the false edges and noise edges and get the lesion edges more accurately.
