TL;DR: A series of normalized and generalized metrics based on the important ingredients of SSIM are constructed and it is shown that such modified measures are valid distance metrics and have many useful properties, among which the most significant ones include quasi-convexity, a region of convexity around the minimizer, and distance preservation under orthogonal or unitary transformations.

TL;DR: This work makes one of the first attempts to employ structural similarity (SSIM) index, a more accurate perceptual image measure, by incorporating it into the framework of sparse signal representation and approximation, and develops a gradient descent algorithm to achieve SSIM-optimal compromise in combining the input and sparse dictionary reconstructed images.

TL;DR: It is shown that well-known full-reference image quality measures can be estimated from the residual image without the reference image, and a procedure is proposed that has the potential to enhance the image quality of given image denoising algorithms.

TL;DR: This work examines the problem of best approximation of signals and images by maximizing the SSIM between them, and examines a very simple algorithm to maximize SSIM with a constrained number of basis functions.

TL;DR: The Pan and Parapan American Games (PA15) are the third largest sporting event in the world and were held in Toronto in the summer of 2015 (10−26 July and 7−15 August) as discussed by the authors.
