For image quality assessment, you use following parameters,
1. MSE - Mean Squared Error
2. PSNR - Peak Signal to Noise Ratio
3. AD - Average Difference
4. SC - Structural Content
5 NK - Normalized Cross-Correlation
6. MD - Maximum Difference
7 LMSE - Laplacian Mean Squared Error
8. NAE - Normalized Absolute Error
For this, check the below link,
