（1）显示一张图片：源代码如下 import cv2 as cv src = cv.imread(“文件路径”) cv.namedWindow(“input image”,cv.WINDOW_AUTOSIZE) cv.imshow(“input image”,src) cv.waitKey(0) (2)对图片进行腐蚀处理 import cv2 as cv src = cv.imread(“文件路径”) cv.namedWindow(“input image”,cv.WINDOW_AUTOSIZE) element = cv.getStructuringElement(cv.MORPH_RECT(5,5)) src_fixed = cv.erode(src,element) imshow(“input image”,src_fixed) cv.waitKey(0) (3)对图片进行模糊处理 import cv2 as cv src = cv.imread(“文件路径”) cv.namedWindow(“input image”,cv.WINDOW_AUTOSIZE) src_fixed = cv.blur（src，（7,7）） imshow(“input image”,src_fixed) cv.waitKey(0)
