Abstract
The object of our research is to embed secret images with high-capacity and high-quality of the stego image. Taking advantage of the small difference among close neighboring pixels, the secret image can be compressed to be a collection of which each component is either a secret pixel or the difference between two neighboring pixels. Then the collection can be entirely embedded into cover image by the improved EMD embedding scheme. The experimental results show that the average bit rate is up to 2.723 bpp and the average PSNR is about 36.4 dB.
