Webb11 apr. 2024 · To quantify performance, we consider peak-signal-to-noise ratio (PSNR) and structural similarity (SSIM) . Table 2 shows the average PSNR and SSIM of each setting. The result verifies that each module benefits the whole system by a certain degree, and the full model achieves the best performance among all. Peak signal-to-noise ratio (PSNR) is an engineering term for the ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation. Because many signals have a very wide dynamic range, PSNR is usually expressed as a logarithmic quantity using … Visa mer PSNR is most easily defined via the mean squared error (MSE). Given a noise-free m×n monochrome image I and its noisy approximation K, MSE is defined as The PSNR (in Visa mer PSNR is most commonly used to measure the quality of reconstruction of lossy compression codecs (e.g., for image compression). The signal in this case is the original data, and the noise is the error introduced by compression. When comparing … Visa mer • Data compression ratio • Perceptual Evaluation of Video Quality (PEVQ) • Structural similarity (SSIM) index • Subjective video quality Visa mer Although a higher PSNR generally indicates that the reconstruction is of higher quality, in some cases it may not. One has to be extremely careful with the range of validity of … Visa mer PSNR-HVS is an extension of PSNR that incorporates properties of the human visual system such as contrast perception. PSNR-HVS-M improves on PSNR-HVS by additionally taking into account visual masking. In a 2007 study, it delivered better … Visa mer
