Hybrid Algorithm to Improve Robustness of Image Watermarking [PDF]
Engineering and Technology Journal, 2015 Watermarking is the process of embedding digital information into any multimedia data such as an image, audio or video file in such a way that intruder cannot be able to trace the signal to protect copyright of intellectual property of the owners.

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 ...

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)

IET Science, Measurement & Technology, 2013 In partial discharge (PD) analyses, there is a need to compare the noise level of measured signals in different conditions and/or after applying certain signal processing algorithms (e.g. noise reduction). Moreover, in PD analyses through modelling approaches, whenever noisy signals should be constructed by adding noise with a desired level to the ...

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

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
