Medical Image Watermarking using Multi Ridgelet and Fast ICA

The medical field along with computer field grows in a rapid manner. In telemedicine and telediagnosis authentication of medical images are very important to the patient ,doctor and Insurance company. The youngsters are also keen in knowing about the treatment methods and procedures. But no one likes to tell about the disease in open hall. So there is always an urge for watermarking of medical images. So in this work we use the concept of multi ridge let and fast independent component analysis. Since multi ridge let is a good way to enhance edges and reduce the noise. In this method we have calculated the structural similarity index measure (SSIM), mean square error(MSE) and peak signal to noise ratio(PSNR) .The experimental results are compared with the existing methods and found to be very effective.
