Block Size Forensic Analysis in Digital Images [PDF]
2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007 In non-intrusive forensic analysis, we wish to find information and properties about a piece of data without any reference to the original data prior to processing. An important first step to forensic analysis is the detection and estimation of block processing.

Image Splicing Localization Using A Multi-Task Fully Convolutional Network (MFCN)
, 2017 In this work, we propose a technique that utilizes a fully convolutional network (FCN) to localize image splicing attacks. We first evaluated a single-task FCN (SFCN) trained only on the surface label.

Contrast Enhancement Estimation for Digital Image Forensics [PDF]
ACM Transactions on Multimedia Computing, Communications, and Applications, 2018 Inconsistency in contrast enhancement can be used to expose image forgeries. In this work, we describe a new method to estimate contrast enhancement operations from a single image. Our method takes advantage of the nature of contrast enhancement as a mapping between pixel values and the distinct characteristics it introduces to the image pixel ...
