SSIM is used for measuring the similarity between two images. The SSIM index is a full reference metric; in other words, … See more The predecessor of SSIM was called Universal Quality Index (UQI), or Wang–Bovik Index, which was developed by Zhou Wang and Alan Bovik in 2001. This evolved, through their collaboration with Hamid Sheikh and See more SSIM has applications in a variety of different problems. Some examples are: • Image Compression: In lossy image compression, information is deliberately discarded to … See more • Mean squared error • Peak signal-to-noise ratio • Video quality See more The SSIM index is calculated on various windows of an image. The measure between two windows $${\displaystyle x}$$ and $${\displaystyle y}$$ of common size $${\displaystyle N\times N}$$ is: with: • See more Due to its popularity, SSIM is often compared to other metrics, including more simple metrics such as MSE and PSNR, and other perceptual image and video quality metrics. SSIM has been repeatedly shown to significantly outperform MSE and its derivates in … See more • Home page • Rust Implementation • C/C++ Implementation • DSSIM C++ Implementation • Chris Lomont's C# Implementation See more promotional rattles for infants
