用python处理图像的色相，饱和度，对比度和亮度

Question

我想知道是否有一种方法可以从python中的图像中提取统计信息或值，例如：亮度，对比度，色调，饱和度和清晰度？

Answer 1

There is no automatic way to do this.

OpenCV can be used for some estimations, like this: https://www.pyimagesearch.com/2015/09/07/blur-detection-with-opencv/

You can also analyse image histogram (use numpy to make it) to detect images with very high or low brightness.
