The Structural Similarity Index (SSIM) is really a perceptual metric that quantifies the image quality degradation this is certainly brought on by processing such as for example information compression or by losings in information transmission. This metric is simply a complete reference that needs 2 images from the exact same shot, this implies 2 graphically identical pictures to your eye that is human. The 2nd image generally is compressed or has a unique quality, which will be the aim of this index. SSIM is normally found in the movie industry, but has also a strong application in photography. SIM really steps the difference that is perceptual two similar images. It cannot judge which of this two is way better: that must definitely be inferred from once you understand that is the initial one and that has been subjected to additional processing such as for instance compression or filters.
In this essay, we will explain to you how exactly to calculate accurately this index between 2 pictures making use of Python.
