图像预处理——归一化操作【Python】

在jpgfile初输入自己需要处理的图像的路径
outdir输入自己的需要保存处理好图像的路径
width, height分别代表宽和高
if filename.endswith('bmp'): 填写自己图像的格式
convertjpg(jpgfile, outdir, 100, 100) 输入地址+输出地址+宽+高

from PIL import Image
import os.path
import glob

jpgfile=' ./imgdata1'
outdir=' ./imgdata2'
def convertjpg(jpgfile, outdir, width, height):
    for parent, dirnames, filenames in os.walk(jpgfile,  followlinks=True):
        for filename in filenames:
            if filename.endswith('bmp'):
                file_path = os.path.join(jpgfile, filename)
                img = Image.open(file_path)
                new_img = img.resize((width, height), Image.BILINEAR)  ###核心代码
                new_img.save(os.path.join(outdir, filename))
if __name__ == "__main__":
    convertjpg(jpgfile, outdir, 100, 100)
