It has been shown that SSIM originates from the two generalised Dice measures and thus inherit their main property scale invariance. Consequently, this property leads to the dependence of the measure on absolute mean and standard deviation values. Similarly, MSE depends on the absolute standard ...
Since PSNR is not effective in terms of human visual judgment, therefore, many researchers utilized the Structural SIMilarity index metric (SSIM), which is a subjective measure that evaluates the dehazing performance in terms of contrast, luminance, and structural coherence between ground truth and de...
As a result, a WebP file is significantly smaller after the compression is applied. The quality is partially degraded depending on the compression level.Lossy compression is also used in JPEG files. However,WebP files are 25-34% smaller than JPEGbased on the same SSIM index. ...
WebP is an image format created by Google for those who need to optimize the size of pictures without quality loss. Such files are 26% smaller than PNG images. In addition, they are 25-34% smaller than JPEG images if one compares them using the SSIM quality index. ...
It is then up to the designers of the models to determine how the weights of the loss terms are employed, depending on the intended application. Thus, it may still be possible that more importance is given to perceptually pleasing content rather than faithful recreations of the original conte...

the model undergoes training. Throughout this phase, the model learns how to adjust its internal parameters to minimize statistical discrepancies between the model’s outputs and the data it was trained on. The goal is tominimize the loss function, the statistical difference between the model’s ...
