Robust Watermarking Scheme Applied to Radiological Medical Images
Roberto Moreno Colín, Claudia Feregrino Uribe, Jose Alberto Martinez Villanueva · IEICE Transactions on Information and Systems · 2008
We present a watermarking scheme that combines data compression and encryption in application to radiological medical images. In this approach we combine the image moment theory and image homogeneity in order to recover the watermark after a geometrical distortion. Image quality is measured with metrics used in image processing, such as PSNR and MSE.
