A 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 8??8 blocks. We propose a novel yet counter intuitive technique to "denoise" JPEG images by adding Gaussian noise. We add a suitable amount of Gaussian noise to a resized and JPEG compressed image so that...
This paper presents a new discrete short time Fourier transform (DSTFT) implementation algorithm, called nonuniform discrete short time Fourier transform (NDSTFT) for real time estimation of power components according to the IEEE Standard 1459-2000. The proposed NDSTFT algorithm is capable of detecting the spectrum of each finite short time section of the power signals at arbitrarily located specified...
