WebJun 24, 2024 · Understanding SSIM. The use of the structural similarity index (SSIM) is widespread. For almost two decades, it has played a major role in image quality assessment in many different research disciplines. Clearly, its merits are indisputable in the research community. However, little deep scrutiny of this index has been performed. WebSSIM stands for Structural Similarity Index and is a perceptual metric to measure similarity of two images. Commonly used loss functions such as L2 (Euclidean Distance) correlate poorly with image quality because they assume pixel-wise independance. For instance blurred images cause large perceptual but small L2 loss. the golf simulator to game ready jbzmb4j7byqWebJun 23, 2009 · Abstract: We introduce a new measure of image similarity called the complex wavelet structural similarity (CW-SSIM) index and show its applicability as a general purpose image similarity index.
