Blind Estimation of Peak Signal to Noise Ratio for JPEG Highly Compressed Images Based on Correlation [PDF]
Jisuanji gongcheng, 2017 Quantization noise is one of thedominant distortions of JPEG image compression,so its amplitude usually needs to be estimated for image quality assessment.Meanwhile,Peak Signal to Noise Ratio(PSNR) estimation method cannot get the original image in the ...

Anti-PT-Symmetric Optical Gyroscope at the Transmission Peak Degeneracy With Enhanced Signal-to-Noise Ratio [PDF]
Journal of Lightwave TechnologyNon-Hermitian sensors have been widely studied for the enhanced response of their eigenvalues in the proximity of exceptional points. However, it has been shown that noise is enhanced in the same way as sensitivity, thus vanishing the advantages of the ...

Edge Detection Operators: Peak Signal to Noise Ratio Based Comparison [PDF]
International Journal of Image, Graphics and Signal Processing, 2014 Edge detection is the vital task in digital image processing. It makes the image segmentation and pattern recognition more comfort. It also helps for object detection. There are many edge detectors available for pre-processing in computer vision. But, Canny, Sobel, Laplacian of Gaussian (LoG), Robert's and Prewitt are most applied algorithms.

PSNR Improvement using Different Prediction Coding in Image Compression
Tikrit Journal of Engineering Sciences, 2010 Differential Pulse Code Modulation (DPCM) is one of the predictive coding techniques. The number of previous pixels employed in the estimate operation is referred to as the order of the predictor. Predictor using one pixel for estimation is called “first

An Adaptive Non-linear Statistical Salt-and-Pepper Noise Removal Algorithm using Interquartile Range
ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2019 This paper presents a salt-and-pepper noise removal scheme using modified mean filter. The proposed method is based on a simple basic concepts of mean filter, where each mean value is calculated from the mathematical formula of interquartile range (IQR)

Robust image transmission performed by SPIHT and turbo-codes [PDF]
Serbian Journal of Electrical Engineering, 2008 This work describes the method for providing robustness to errors from a binary symmetric channel for the SPIHT image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets. Punctured turbo codes are
