摘要：In this paper we have proposed algorithms that are based on adaptive threshold method. Reversible watermarking scheme employed in this scheme improves Fourier Transform. First threshold map for image has been created and then image has been divided into different blocks. In last threshold map being set for each block. This improves image information storing capacity and original image can be obtained back. In this algorithm image can be recoded, embedded and transmitted simultaneously. The scheme can easily be used in e-diagnosis applications such as teleconsulting, tele-surgery and tele-diagnosis.
