Structural similarity Index (for 2D data)

notion image

Luminance - by considering average value $μ$

Contrast - by considering variance value $σ_x, σ_y$

Structure - by considering correlation value $σ_{xy}$

Loss Function

L_{SSIM}=1−SSIM(x,y)

Structural similarity

The structural similarity index measure (SSIM) is a method for predicting the perceived quality of digital television and cinematic pictures, as well as other kinds of digital images and videos. SSIM is used for measuring the similarity between two images. The SSIM index is a full reference metric; in other words, the measurement or prediction of image quality is based on an initial uncompressed or distortion-free image as reference.
