Abstract:In order to reversibly hide information in images with high capacity, an self-adaptive method is proposed in this paper by optimally selecting the differential direction. By dividing image into blocks, differences for adjacent pixel pairs in each blocks are computed in multi-directions. Based on the statistics of these differences, the optimal and self-adaptive strategy for increasing embedding capacity is introduced. The experimental results demonstrate that a significant improvement of embedding capacity is achieved, while the qualities of images is maintained.
