Robust Blind Watermarking Scheme Using Wave Atoms,m against nine types of attacks like JPEG compression, Gaussian Noise addition, Median Filtering, Salt and Pepper noise, etc. They are carried out using Matlab Software. The experimental results demonstrate that the proposed algorithms have great robustness against various imaging attacks.

Kontext: Die Ausgangsbasis der Untersuchunge alignment points is increased by performing a simple plane transform on one of the shares. This results in the same secret being recovered when the shares correctly aligned. The technique has also been extended to encompass multiple secrets, each of which can be recovered depending on the type of transformation performed on the shares.

Discriminating Computer Graphics Images and Natural Images Using Hidden Markov Tree Model,blem in image classification, too. In this paper, we propose using HMT(hidden Markov tree) to classifying natural images and computer graphics images. A set of features are derived from HMT model parameters and its effect is verified by experiment. The average accuracy is up to 84.6%.

An Efficient Pattern Substitution Watermarking Method for Binary Images,derably for un-overlapping version of the PS method. Experiment results show that our method works well on decreasing the size of location map. Comparison results with the original PS method demonstrate that the proposed method achieves more embedding capacity and higher PSNR value due to the reduced size of the location map.

Comparing with the existing spatial domain reversible watermark methods, the proposed method can achieve much better PSNR value at the high embedding rate. Experimental results prove the effectiveness of the proposed watermarking scheme.
