[人工智能]python批量填充图像边缘并保存

import os
import cv2 as cv

path = './LowRes' #文件夹目录
savepath = "./NewLowRes"  # 保存文件夹
files= os.listdir(path) #得到文件夹下的所有文件名称
total_num = len(files)  #得到文件夹中图像的个数

for i in range(total_num):
    filename = path + '/' + files[i]
    img = cv.imread(filename)
    top_size, bottom_size, left_size, right_size = (0, 0, 18, 18)
    constant = cv.copyMakeBorder(img, top_size, bottom_size, left_size, right_size, cv.BORDER_CONSTANT,
                                 value=(0, 0, 0))

    #保存图像
    savejpg_name = savepath + '/LowRes' + str(i + 1) + '.jpg'  #拼接保存图像的地址
    cv.imwrite(savejpg_name, constant)
