Lecture Notes in Computer Science, 2018
JPEG is wildly used for image compression, which inevitably introduces some distortions, such as blocking artifacts and blurring. Peak Signal to Noise Ratio (PSNR) is the most widely used objective criterion to evaluate image distortion, which is a full reference image quality assessment and requires original image as the reference.

Image Sharpening with Optimized PSNR

2019 IEEE International Conference on Signal and Image Processing Applications (ICSIPA), 2019
A family of matrix filters are introduced through approximations to directional digital derivatives. Images can be sharpened by combining all the eight directional filtered images together. The two parameters in the filter family are determined by desired PSNR so that a given image is sharpened with optimized PSNR.

PSNR vs SSIM: imperceptibility quality assessment for image steganography

Multimedia Tools and Applications, 2020
Peak signal to noise ratio (PSNR) and structural index similarity (SSIM) are two measuring tools that are widely used in image quality assessment. Especially in the steganography image, these two measuring instruments are used to measure the quality of imperceptibility.

Mazdak Technique for PSNR Estimation in Audio Steganography

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.
