Template matching of occluded object under low PSNR
Digital Signal Processing, 2013A robust template matching using occlusion-free correlation (OFC) coefficient is presented in this paper for the purpose of locating objects partially occluded under low PSNR (Peak Signal to Noise Ratio) environment. The OFC coefficient can effectively eliminate the negative effect of occlusion on matching score, resulting in providing better accuracy ...

A gray-level clustering reduction algorithm with the least PSNR
Expert Systems with Applications, 2011Gray-level clustering is an important procedure in image processing, which reduces the gray-level intensity of an image. In order to display a high gray-level image on low gray-level device screen, a good gray-level clustering reduction algorithm is necessary to complete this task.

What statistics is PSNR related using JPEG2000
2008 IEEE Conference on Cybernetics and Intelligent Systems, 2008JPEG2000 encoder is well designed, it makes full use of the redundant information among the images. Many of us may have the experience that when compress variety of images of different types using it, the peak signal-to-noise ratio (PSNR) values vary widely from image to image.

Embedding data in edge boundaries with high PSNR
2011 7th International Conference on Emerging Technologies, 2011Data hiding is one of the most significant aspects in information security. Generally data embedding is achieved in communication, image, text, voice, or multimedia content for copyright, military communication, authentication and many other purposes.

An Algorithm to Control Watermarking Capacity Using PSNR
Advanced Materials Research, 2014Some existing methods for estimating image watermarking capacity may degenerate the quality of stego-image when the estimated capacity is achieved. In this paper, based on the Region of Interest (ROI) model, we discuss on the capacity problem and the quality of stego-images using PSNR.

On the mDCT-PSNR image quality index
2009 International Workshop on Quality of Multimedia Experience, 2009Full reference image quality indices assign a quality index to a pair of an undistorted reference image and a distorted image to be assessed; the quality of the index itself is then defined by its ability to predict the outcome of subjective tests performed by human observers judging the quality of the same image pair.

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.
