python+opencv检测图像清晰度

直接上代码，list_jian.txt为待检测图像路径列表

import cv2
import numpy as np
import os

for path in open("list_jian.txt"):
    path = path.replace('\n', '') #去除换行符号
    img = cv2.imread(path, 1)
    width,height = img.shape[:2][::-1]
    img_resize = cv2.resize(img,(int(width*1.0),int(height*1.0)),interpolation=cv2.INTER_CUBIC)
    img_gray = cv2.cvtColor(img_resize,cv2.COLOR_RGB2GRAY)
    imageVar = cv2.Laplacian(img_gray, cv2.CV_64F).var() #图像模糊度
    print('>>>',path)
    print(">>>",int(imageVar))
