Difference between SNR and PSNR - image processing

WebJun 7, 2024 · At TestDevLab, we most commonly calculate the PSNR results for brightness (Y or the luma component) as that is the information that people are most sensitive to. As mentioned earlier, PSNR is a non-linear full-reference metric. Generally, PSNR is measured in decibels on a scale from 0-60. However, PSNR does have its drawbacks. WebThis ratio is used as a quality measurement between the original and a compressed image. The higher the PSNR, the better the quality of the compressed, or reconstructed image. … did nestle refuse to pull out of russia
