Code error in ssim.py

[rongliangzi]

In src->ssim.py, line 99:
img1 = (img1 + 1e-12) / (img2.max() + 1e-12)
should that be
img1 = (img1 + 1e-12) / (img1.max() + 1e-12)
?

Also in src->ssim.py
according to the paper proposing msssim
msssim should be calculated as
cs[0:4]**weights[0:4] * ssim[4]**weights[4]
not
ssim[0:]**weights[0:]
Am I right?
