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)
