PSNRään
PSNR is a metric used to measure the quality of reconstruction of a lossy compression code, such as that of digital images or video. It is defined as the ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation. PSNR is most commonly used to measure the quality of reconstruction of lossy compressed images or videos. The higher the PSNR value, the better the quality of the reconstructed image or video.
PSNR is calculated using the mean squared error (MSE) between the original and reconstructed images. The MSE
PSNR is a widely used metric, but it has some limitations. For example, it does not always
