Title: Simulation Model for Medical Images Watermarking using Wavelet Transform and DCT
Keywords: Medical Image Watermarking, Complex Hadamard Transform, Unitary Transforms, Matlab Simulation
Abstract: A simulation model of algorithm for digital watermarking of medical images using complex Hadamard transform is presented. The model is implemented on a signal processor TMS 320C6713 and its experiments indicate it can be used in real-time systems. The developed algorithm for watermarking allow high detection of unauthorized access or attacks on the included watermark. The obtained experimental results for some attacks over the test medical images are made on the base of mean-squared error and signal to noise ratio of the reconstructed images.
