Robust and High Capacity Watermaking Scheme for Medical Images Based on Contourlet Transform

摘要

This paper shows probability of watermarking using Contourlet transform domain under trade-off increasing payload. We continue to develop our previous methods to achieve better results. Experiment results prove our technique is robust from desynchronization attacks as well as other common attacks with a high payload especially for medical images. Our approach improves the performance of the watermarking algorithm on comparing to other techniques and showing in experimental results.
