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 ...

Added 64bit stride support to various operators limited to 32bit strides to avoid performance regressions: AdaptiveThreshold, AdvCvtColor, AverageBlur, BilateralFilter, BrightnessContrast, ColorTwist, BoxBlur, CenterCrop, ConvertTo, CopyMakeBorder, CustomCrop, GaussianNoise, Gaussian, Flip, HistogramEq, Join...
Briefly, the isotope profiles of a given peptide are converted to an ASCII file, and the relative intensities are determined by fitting the data to a series of Gaussian peaks centered at 1-Da intervals using Origin software. Parameters of the fit are constrained to (i) the center of the ...

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 ...
