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 ...

Fixed-PSNR Lossy Compression for Scientific Data [PDF]
2018 IEEE International Conference on Cluster Computing (CLUSTER), 2018 Error-controlled lossy compression has been studied for years because of extremely large volumes of data being produced by today's scientific simulations. None of existing lossy compressors, however, allow users to fix the peak signal-to-noise ratio (PSNR) during compression, although PSNR has been considered as one of the most significant indicators ...

A perceptually relevant shearlet-based adaptation of the PSNR [PDF]
2017 IEEE International Conference on Image Processing (ICIP), 2017 Although being one of the simplest and most widely used image quality metrics (IQMs) the peak signal-to-noise ratio (PSNR) correlates only poorly with visual quality as perceived by humans. Based on an analysis of the non-linear mapping from PSNR to mean opinion scores (MOS) we identify a functional mapping parameter to adapt the PSNR perceptually ...

Mazdak Technique for PSNR Estimation in Audio Steganography [PDF]
Applied Mechanics and Materials, 2012 A novel method to estimate PSNR of the result of audio steganography before embedding is presented. Estimated PSNR by proposed linear interpolation formula was tested and the result was almost the same with the obtained PSNR in practical way.

PSNR evaluation and alignment recovery for mobile satellite video broadcasting [PDF]
2012 6th Advanced Satellite Multimedia Systems Conference (ASMS) and 12th Signal Processing for Space Communications Workshop (SPSC), 2012 Peak Signal-to-Noise Ratio (PSNR) is the simplest and most widely used objective video quality evaluation method. However, traditional PSNR calculations do not take packet loss into account thus giving an inaccurate representation of the video quality.

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.

High PSNR based Image Steganography [PDF]
International Journal of Advanced Engineering Research and Science, 2019 Steganography is a method for inserting digital data within a different digital medium like text, pictures, sound signals, or film signals, while not exposing its occurrence in the medium.

Improving Psnr-Based Quality Metrics Performance For Point Cloud Geometry [PDF]
2020 IEEE International Conference on Image Processing (ICIP), 2020 An increased interest in immersive applications has drawn attention to emerging 3D imaging representation formats, notably light fields and point clouds (PCs). Nowadays, PCs are one of the most popular 3D media formats, due to recent developments in PC acquisition, namely with new depth sensors and signal processing algorithms.

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
