python实现对任意大小图片均匀切割的示例

改代码是在windows系统下打开路径和保存路径换成自己的就可以啦~importnumpyasnpimportmatplotlibimp

改代码是在windows 系统下

打开路径和保存路径换成自己的就可以啦~

import numpy as np
import matplotlib
import os
 
def img_seg(dir):
 files = os.listdir(dir)
 for file in files:
 a, b = os.path.splitext(file)
 img = Image.open(os.path.join(dir + "\\" + file))
 hight, width = img.size
 w = 256
 id = 1
 i = 0
 while (i + w <= hight):
 j = 0
 while (j + w <= width):
 new_img = img.crop((i, j, i + w, j + w))
 #rename = "D:\\labelme\\images\\"
 rename = "D:\\labelme\\annotations\\"
 new_img.save(rename + a + "_" + str(id) + b)
 id += 1
 j += w
 i = i + w
 
 
if __name__ == '__main__':
 #path = "D:\\labelme\\data\\images\\train"
 path = "D:\\labelme\\data\\dataset_png"
 img_seg(path)
