چکیده انگلیسی
In this paper, a novel section-wise exploiting modification direction (EMD) method is proposed. By using section-wise strategy, the proposed method combines several pixel groups of the cover image together to indicate adjusting modification directions. In each group, the data hiding is performed by the EMD method. Theoretically, we have proved that the modification directions of our section-wise approach is far from the EMD method. The experimental results show that the section-wise strategy can improve the embedding efficiency and the visual quality further than the EMD method, and reduce the possibility of detection.
