我怎样才能更快地执行 cv2.imcode() ？
how can I perform cv2.imcode() faster?
有没有办法以更快的方式执行下面的代码行？
arr = cv2.imdecode(np.frombuffer(tar.extractfile(img).read(), cv2.IMREAD_COLOR)
这要快得多：
from PIL import Image
import io
import numpy as np
import tarfile
f = io.BytesIO()
f.write(tar.extractfile(tiff).read())
f.seek(0)
arr = np.array(Image.open(f))
