Appendix C: Definition of PSNR
2009PSNR is calculated by summing up the squared pixel differences between the distorted and the source video signal. It has to be calculated for each component separately.

Enhancing Image Watermarking With Adaptive Embedding Parameter and PSNR Guarantee
IEEE Transactions on Multimedia, 2019Watermarking plays an important role in identifying the copyright of an image and related issues. The state-of-the-art watermark embedding schemes, spread spectrum and quantization, suffer from host signal interference (HSI) and scaling attacks, respectively.

PSNR evaluation and alignment recovery for mobile satellite video broadcasting
2012 6th Advanced Satellite Multimedia Systems Conference (ASMS) and 12th Signal Processing for Space Communications Workshop (SPSC), 2012Peak 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 PSNR-Controllable Data Hiding Algorithm Based on LSBs Substitution
2015 IEEE Global Communications Conference (GLOBECOM), 2014There are more and more systems using mobile devices to perform sensing task, but it increases the risk of leakage of personal privacy and data. Data hiding is one of the important ways for information security. Even many data hiding algorithms have worked on providing more hiding capacity or higher PSNR, there are few algorithms that can achieve ...

No-reference PSNR Estimation Based on HEVC Coding
2018 10th International Conference on Communication Software and Networks (ICCSN), 2018With the continuous rising of video applications, the compression of video information has become necessary. As the newest video coding standard, HEVC achieves twice the compression ratio of H.264 under the same video quality. But meanwhile, it produces certain quality impairments, so it's necessary to do video quality evaluation on HEVC coding.

A Virtual View PSNR Estimation Method for 3-D Videos
IEEE Transactions on Broadcasting, 2016In three-dimensional videos (3-DVs) with ${n}$ -view texture videos plus ${n}$ -view depth maps, virtual views can be synthesized from neighboring texture videos and the associated depth maps. To evaluate the system performance or guide the rate-distortion-optimization process of 3-DV coding, the distortion/PSNR of the virtual view should be ...

Video Matching by One-Dimensional PSNR Profile
Applied Mechanics and Materials, 2013This paper addresses a compact framework to matching video sequences through a PSNR-based profile. This simplify video profile is suitable to matching process when apply in disordered undersea videos. As opposed to using color and motion feature across the video sequence, we use the image quality of successive frames to be a feature of videos.
