JPEG 2000 is a lossy integer-to-integer transform-based compression method that first quantizes the separable 2-D wavelet transform coefficients, then entropy codes them. The imag...
Correlated steganography considers the case in which the cover Work is chosen to be correlated with the covert message that is to be hidden. The advantage of this is that, at leas...
In this paper, we use the previously proposed calibrated DCT features [9] to construct a Support Vector Machine classifier for JPEG images capable of recognizing which steganograp...
We explore several local and global strategies for adaptive scan ordering of transform coefficients in JPEG XR/HD Photo. This codec applies a global adaptive scan-order heuristic ...

As JPEG has become an international standard for image compression, we present techniques that allow the processing of an image in the JPEG-compressed" domain. The goal is to...
