批量resize

import cv2
import os

from PIL import Image
import os
from PIL import Image


image_size = 384
source_path = "/omnisky4/l/Medical-transformer/data/NUAA/images/"
target_path = "/omnisky4/l/Medical-transformer/data/NUAA384/images/"

if not os.path.exists(target_path):
    os.makedirs(target_path)

image_list = os.listdir(source_path)
print(image_list)

for file in image_list:

    image_source = cv2.imread(source_path + file)
    image = cv2.resize(image_source, (image_size, image_size))
    cv2.imwrite(target_path + file, image)

print("批量处理完成")

单张resize

from PIL import Image

im1 = cv2.imread('/omnisky4/l/Medical-transformer/data/NUAA_256/masks/Misc_8.png')
cv2.imshow('image1', im1)
im2 = cv2.resize(im1, (256,256), interpolation=cv2.INTER_CUBIC)
cv2.imshow('image2', im2)
cv2.imwrite('/omnisky4/l/Medical-transformer/data/NUAA_256/masks/Misc_8.png', im2)
