JPEG Steganography and Synchronization of DCT Coefficients for a Given Development Pipeline
Théo Taburet, Patrick Bas, Wadih Sawaya +1
This short paper proposes to use the statistical analysis of the correlation between DCT coefficients to design a new synchronization strategy that can be used for cost-based stega…
A new Edge Detector Based on Parametric Surface Model: Regression Surface Descriptor
Rémi Cogranne, Rémi Slysz, Laurence Moreau +1
In this paper we present a new methodology for edge detection in digital images. The first originality of the proposed method is to consider image content as a parametric surface.…
Determining JPEG Image Standard Quality Factor from the Quantization Tables
Rémi Cogranne
Identifying the quality factor of JPEG images is very useful for applications in digital image forensics. Though several command-line tools exist and are used in widely used softwa…
Statistical Detection of LSB Matching Using Hypothesis Testing Theory
Rémi Cogranne, Cathel Zitzmann, Florent Retraint +3
This paper investigates the detection of information hidden by the Least Significant Bit (LSB) matching scheme. In a theoretical context of known image media parameters, two import…
