Steganalysis is the technique for attacking steganography methods to detect the secret message. Image steganalysis can be viewed as a two class classification problem. To this end, this book has two contributions. First, to define grayscale image steganalysis based on Fuzzy c-Means Clustering the objective of the formulated fuzzy problem is to construct two fuzzy clusters: cover image and stego image clusters. The second contribution is to use Histogram Characteristic Function (HCF) and calibrated HCF by downsampling detectors and propose a new detector called calibrated HCF by Haar wavelet. T...
