Reversible Data Hiding By Using Modified Difference Expansion

摘要：

In this paper, we propose a reversible data hiding method with low time complexity and high embedding capacity for gray-scale images. This method presents a blockbased lossless data hiding schema to utilize the similarity between neighborhood pixels in the block to im prove the marked-image quality. The experimental results show that our method has increased the hiding capacity with keeping acceptable marked image quality.
