/ Characteristics / SNR/PSNR
SNR (Signal-to-Noise Ratio) and PSNR (Peak Signal-to-Noise Ratio) estimate the quality of the reconstructed image compared to the original image.
The specific value of this quantity does not say anything, the reconstruction quality measure is obtained by comparing the results of two differently reconstructed images.

where f is the original image, F is the reconstructed image, N is the total number of pixels in the image.
Using the following relation we can calculate the error image.

The image is loaded from the main program window. In the working window, specify the location of the second image.
Then the SNR and PSNR values are calculated. Both values are displayed, and the error difference image is also displayed.
