KITTI-MOT图片形式的Annotation解码成一般形式

from PIL import Image
import glob
import os

# 对图片解码
def decode_mask(path): 
    out_base_path = '...../KITTI-tracking/decode_mask' #输出文件夹 
    folders = sorted(glob.glob(os.path.join(path, '*')))
    for folder in folders:
        temp_1 = folder.split('/')
        samples = []
        samples.extend(sorted(glob.glob(os.path.join(folder, '*.png'))))
        out_path = os.path.join(out_base_path, '{}'.format(temp_1[-1]))
        os.makedirs(out_path, exist_ok=True)
        for sample in samples:
            temp_2 = sample.split('/')
            mask = Image.open(sample)
            mask_8bits = mask.convert('L')
            out = os.path.join(out_path, temp_2[-1])
            mask_8bits.save(os.path.join(out_path,out))
