open-cv对图像实现两次上采样，提升分辨率

# -*- coding: utf-8 -*-
import cv2
import numpy as np
import matplotlib.pyplot as plt
import os
# 需要改动的只有两部分
# path原图像路径，path2高分辨率图像路径

path = r'C:UserssunDesktopdata24trainNo-Anomaly'
path2 = r'C:UserssunDesktopdata244trainN'

picture_name = os.listdir(path)
for picture_names in picture_name:
   picture_path = os.path.join(path, picture_names)
   # 图像上采样
   img1 = cv2.imread(picture_path)
   img2 = cv2.pyrUp(img1)
   img3 = cv2.pyrUp(img2)

   new_picture = os.path.join(path2, picture_names)
   cv2.imwrite(new_picture, img3)
