On the Computation of PSNR for a Set of Images or Video [PDF]
2021 Picture Coding Symposium (PCS), 2021 When comparing learned image/video restoration and compression methods, it is common to report peak-signal to noise ratio (PSNR) results. However, there does not exist a generally agreed upon practice to compute PSNR for sets of images or video. Some authors report average of individual image/frame PSNR, which is equivalent to computing a single PSNR ...

PSNR Improvement Using Different Prediction Coding
Tikrit Journal of Engineering Sciences, 2015 Differential Pulse Code Modulation (DPCM) is one of the predictive coding techniques. The number of previous pixels employed in the estimate operation is referred to as the order of the predictor. Predictor using one pixel for estimation is called “first

Weighted Fuzzy-Based PSNR for Watermarking
CoRR, 2021 One of the problems of conventional visual quality evaluation criteria such as PSNR and MSE is the lack of appropriate standards based on the human visual system (HVS). They are calculated based on the difference of the corresponding pixels in the original and manipulated image.

SURVEY OF SUPER RESOLUTION TECHNIQUES [PDF]
ICTACT Journal on Image and Video Processing, 2019 The key objective of super-resolution imaging is the process of reconstructing a high resolution image from one or a set of low resolution images, to overcome the ill-posed conditions of the image capturing process to get better visualization.

A subpixel registration algorithm for low PSNR images [PDF]
2012 IEEE Fifth International Conference on Advanced Computational Intelligence (ICACI), 2012 This paper presents a fast algorithm for obtaining high-accuracy subpixel translation of low PSNR images. Instead of locating the maximum point on the upsampled images or fitting the peak of correlation surface, the proposed algorithm is based on the measurement of centroid on the cross correlation surface by Modified Moment method.
