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
