Analysis for Watermark in Medical Image using Watermarking with Wavelet Transform and DCT

An analysis for increasing the transparency of digital watermarking of medical images, using discrete Wavelet transform and DCT is presented. The analysis ensures watermarking with high resistant of the watermark, to commonly used types of malicious image processing. The results for the analysis of the transparency on the watermark image is based on the signal to noise ration and mean-square error after watermarking the image.
