Gaussian noise additionJPEG compressionbilinear interpolationimage forensicsimage resizingA common problem affecting most image resizing detection algorithms is that they are susceptible to JPEG compression. This is because JPEG introduces periodic artifacts, as it works on 88 blocks. We propose a novel ...
편집:Mohammad Abouali2014년 10월 16일 채택된 답변:Mohammad Abouali Hi, i would like to know how to add a Gaussian noise distribution of SD 1% and 0 mean to a uniform grid consisting of particle pairs. (P1x,P1y),(P2x,P2y) contain the location of the points in my...

Gaussian/Uniform noise in the range of 28-24 dB is added to the image and the images thus formed are passed to the re-sampling detector. The detector outputs are averaged to get a final output from which re-sampling can be detected even at lower QFs. We consider two re-sampling ...
The authors also found that by approximating the symmetrical histograms by a Gaussian distribution and skewed ones by a chi-squared distribution, the noise could be reproduced to an extent that well satisfies the professional. Comparison of professional's noise to film grain showed that they have ...
According to the zero intermediate frequency Gaussian white noise adding method, modular design can be achieved.陆连伟宋杰
The symmetrical histograms were approximated by Gaussian distribution and skewed ones by chi-square distribution. The images on which the noise was reproduced were judged by the professional himself to be satisfactory enough. As the professional said he added the noise so that "it looked like the ...
