WebEssentially, --tune=psnr uses PSNR as the algo for determining how to distort the image. Works well, the fastest, but it's not the best. --tune=ssim uses SSIM, and it works quite well with live-action, and it is a bit slower (it is not really noticeable though). It absolutely butchers animation, so don't use it for any kind of animation. WebMay 26, 2024 · Peak Signal to Noise Ratio (PSNR): Structural Similarity Index Measure (SSIM) PSNR. PSNR is a ratio between the maximum possible power of a signal and the power of corrupting noise that affects the fidelity of its representation. PSNR is often used to control the quality of digital signal transmission.

Image Quality Metrics: PSNR vs. SSIM - IEEE Xplore

WebJul 17, 2024 · The Structural Similarity Index (SSIM) is a perceptual metric that quantifies the image quality degradation that is caused by processing such as data compression or by losses in data transmission. This metric is basically a full reference that requires 2 images from the same shot, this means 2 graphically identical images to the human eye.
