Off-By-One Implementation Error in J-UNIWARD

no code implementations31 May 2023 Benedikt Lorch

To this end, J-UNIWARD first assigns to each DCT coefficient an embedding cost calculated based on the image's Wavelet residual, and then uses a coding method that minimizes the cost while embedding the desired payload.

Toward Reliable Models for Authenticating Multimedia Content: Detecting Resampling Artifacts With Bayesian Neural Networks

no code implementations28 Jul 2020 Anatol Maier, Benedikt Lorch, Christian Riess

To this end, we propose to use Bayesian neural networks (BNN), which combine the power of deep neural networks with the rigorous probabilistic formulation of a Bayesian framework.
