WebAs a result, many image processing methodologies have been recently extended to take advantage of alternative visual quality measures, the most prominent of which is the Structural Similarity Index Measure (SSIM). The superiority of the latter over Euclidean-based metrics have been demonstrated in several studies.
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. WebWang et al., in their revolutionary work on the structural similarity index or SSIM , argued that human visual perception is highly sensitive to structural information. The SSIM index incorporates luminance, contrast, and structural comparison information and achieves a very good correlation with the mean opinion scores (MOS) of human observers.
