- Peak signal-to-noise ratio(PSNR) is an engineering term for the ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation.

The structural similarity (SSIM) index is a method for predicting the perceived quality of digital television and cinematic pictures, as well as other kinds of digital images and videos. The SSIM index is calculated on various windows of an image.
- The measure between two windows
and
of common size N×N is:
- The measure between two windows
This Repository was created to experiment with the thesis below.
Performance can be measured in all images, even if you don't use the thesis below!
