Helmut Ungrad,Willibald Winkler,Andrzej Wiszniewskier with variants of Weighted Stego-image (WS) analysis have materialized as the most accurate. In this paper, we show that further surprisingly significant improvement is possible with machine–learning based detectors utilizing co-occurrences of neighboring noise residuals as features. Such features
