一、模糊操作

#!/usr/bin/env python
# _*_ coding:utf-8 _*_
import cv2 as cv
import numpy as np


def blur_demo(image):
    dst = cv.blur(image, (15, 1))
    cv.imshow("blur_demo", dst)

src = cv.imread("F:\miao3.png")
cv.namedWindow("input image", cv.WINDOW_AUTOSIZE)
cv.imshow("input image", src)
blur_demo(src)
cv.waitKey(0)
cv.destroyAllWindows()

运行结果，如图：

二、锐化操作

#!/usr/bin/env python
# _*_ coding:utf-8 _*_
import cv2 as cv
import numpy as np


def custom_blur_demo(image):
    kernel = np.array([[0, -1, 0], [-1, 5, -1], [0, -1, 0]], np.float32) #锐化
    dst = cv.filter2D(image, -1, kernel=kernel)
    cv.imshow("custom_blur_demo", dst)

src = cv.imread("F:\miao3.png")
cv.namedWindow("input image", cv.WINDOW_AUTOSIZE)
cv.imshow("input image", src)
custom_blur_demo(src)
cv.waitKey(0)
cv.destroyAllWindows()

运行结果，如下图：
