image_dehaze's Issues

请问这里面的代码和参数是按照何博士写的吗

The code of AtmLight part is wrong.

Your code only get axis [0,0] as the A value. Because the code of 'indices' shows wrong. All the values in 'indices' array are 0. You need change 'dark.reshape(imsz,1)' to 'dark.reshape(1, imsz)'.

The difference from what Dr. Ho's article shows

I tried images that Dr. Ho's paper employed, it turns out differs a lot

Cannot get the example image

Hi,

I tried to run the dehaze.py. But the resulting image is different from the J.png for the sky region.
Can you give some hints on it? Is this related to the cv2 and numpy versions or some parameters?
