High capacity audio watermarking using FFT amplitude interpolation [PDF]

, 2009
An audio watermarking technique in the frequency domain which takes advantage of interpolation is proposed. Interpolated FFT samples are used to generate imperceptible marks. The experimental results show that the suggested method has very high capacity (

TrISec: Training Data-Unaware Imperceptible Security Attacks on Deep Neural Networks

, 2019
Most of the data manipulation attacks on deep neural networks (DNNs) during the training stage introduce a perceptible noise that can be catered by preprocessing during inference or can be identified during the validation phase. Therefore, data poisoning

Adaptive scaling factors based on the impact of selected DCT coefficients for image watermarking

Journal of King Saud University: Computer and Information Sciences, 2022
Image watermarking technique aims at high imperceptibility of the embedded watermark with minimal distortion in the watermarked images. In frequency-domain, block-based Discrete Cosine Transform (DCT) is a popular method which can be improved by ...
