Statistical model of quantized DCT coefficients : application in the steganalysis of Jsteg algorithm
The goal of this paper is to propose a statistical model of quantized discrete cosine transform (DCT) coefficients. It relies on a mathematical framework of studying the image processing pipeline of a typical digital camera instead of fitting empirical data with a variety of popular models proposed...
