Abstract

Telemedicine is a general practice among remote areas. There is a chance of modifying in medical images intentionally or accidently if transmitted through open network. The medical practitioner has to verify region of interest (ROI), the diagnosis area of the received medical images before rendering any decision report. In this paper, a medical image watermarking scheme using DCT domain is discussed. The decision area (ROI) is to be separated using Fuzzy c- means and embed watermark in region of non- interest (RONI) using M-ary modulation. The effectiveness of the system is experimentally proved for different MRI medical images using different quality measures as PSNR, MSE, NRMSE, MAE and NCC and revealed that the proposed scheme produced a preferable quality of watermarked medical images.
