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.

Visual-PSNR measure of image quality
Journal of Visual Communication and Image Representation, 2014Abstract Objective assessment of image quality is important in numerous image and video processing applications. Many objective measures of image quality have been developed for this purpose, of which peak signal-to-noise ratio PSNR is one of the simplest and commonly used. However, it sometimes does not match well with objective mean opinion scores (

PSNR and MSE based investigation of LSB
2016 International Conference on Computational Techniques in Information and Communication Technologies (ICCTICT), 2016This paper provide the detail study of LSB Steganography method and analyzes the PSNR and MSE of LSB data hiding technique on the basis of different message sizes i.e 2KB, 4KB, 8KB in different 256*256 gray scale images in spatial domain. Also a investigation of 128*128 on 1KB and 2KB are given.

A new combined PSNR for objective video quality assessment
2017 IEEE International Conference on Multimedia and Expo (ICME), 2017In video coding, quality evaluation is important for improving the coding efficiency. Usually Peak Signal-to-Noise Ratio (PSNR) is utilized to measure the performance of different coding techniques. During the video coding process in YCbCr color space, there are three PSNRs, one for each color component.

A referenceless PSNR estimator of compressed JPEG images
2016 26th International Conference Radioelektronika (RADIOELEKTRONIKA), 2016The paper develops a universal procedure to estimate the level of distortions caused by the JPEG compression of an image of any structural content. To determine the quality, we use the PSNR metric. The procedure allows us to employ different stochastic models to predict the variance of the DCT coefficient quantization noise.

No-Reference Estimation of the Coding PSNR for H.264-Coded Sequences
IEEE Transactions on Consumer Electronics, 2007In this article an algorithm for the evaluation of the picture quality of H.264-coded video sequences is introduced. As a measure of picture quality the peak signal to noise ratio (PSNR) is used. While the computation of the PSNR usually considers a reference signal in comparison to the distorted video sequence, the proposed algorithm uses the coded ...

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 ...
