Mazdak Technique for PSNR Estimation in Audio Steganography
Applied Mechanics and Materials, 2012A 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
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.

Efficient Hierarchical Segmentation Based On PSNR For Low Bit Rate Coding
Proceedings of APCCAS'96 - Asia Pacific Conference on Circuits and Systems, 2002This paper presents a hierarchical morphological segmentation algorithm based on PSNR for each region. The algorithm follows a top-down procedure. It first takes into account the global information and produces a coarse segmentation, that is, with a small number of regions. Then, each region has different quality in coarse segmented image.

Efficient PSNR scalable coding of motion compensated prediction residuals
2006 8th international Conference on Signal Processing, 2006The improvement of video coding is depended on how to reduce the use of motion compensation prediction residuals (MCPR), which is also called displaced frame difference. This paper has put forward a PSNR scalable image coding method based on bit-plane technique and lifting scheme wavelet. Combining the statistical property of MCPR and HVS property, the

MPEG-4 AVC No-Reference PSNR Estimator: The Framework
2007 17th International Conference Radioelektronika, 2007This contribution presents a concept of a novel objective metric for MPEG-4 AVC / H.264 video no-reference quality evaluation. The metric should operate on the encoded bitstream only, bringing the great benefit of reducing computational complexity as no pixel decoding is necessary.

Low PSNR High Fidelity Image Compression Using Surrounding Pixels
2018 International Conference on Circuits and Systems in Digital Enterprise Technology (ICCSDET), 2018Data compression is important to reduce the transmission delays and to ensure efficient utilization of bandwidth and storage space. As images constitute a major part of the data being stored and communicated, image compression is of great importance. However, compression should not degrade the quality of the image to an unacceptable level.

Analysis of Power System Harmonics Using PSNR Metric
2017In recent times there has been a wide interest in micro grids. One area of concern in micro grids is the generation of harmonics by active devices such as converters and FACTS devices used for reactive power compensation. The currently available literature focuses on the number of operations and fundamental cycles for estimating harmonics. This usually
