In this paper I proposed a novelty of medical image watermarking using transformed domain techniques. There are
different types of medical images consisting of different information. In this paper the watermark embedding algorithm is
three steps. First one is the cover image is divided in to four parts with equal size. Second step is the watermark images are
going to be embedded in to those four parts by using DWT & SVD transforms and finally combining the four parts in to a
single image to obtain watermarked image. By performing the reverse embedding process at the receiver side I am getting
watermark images. Finally I achieved the good results for quality measures MSE, PSNR, NCC, SD, ME.
