Image structural similarity (SSIM). In TypeScript/JavaScript. For browser/server.
Fast single-threaded SSIM (Structural Similarity Index) metric for CI visual testing
The structural similarity (SSIM) index is a method for measuring the similarity between two images. The SSIM index is a full reference metric; in other words, the measuring of image quality based on an initial uncompressed or distortion-free image as reference. SSIM is designed to improve on traditional methods like peak signal-to-noise ratio (PSNR) and mean squared error (MSE), which have proven to be inconsistent with human eye perception.
