In this paper, we experimental investigate if the current reversible data hiding schemes are detectable. By modeling the distributions of horizontal pixel difference of natural image using generalized Gaussian model, we find that the horizontal difference histogram of watermarked image is significantly altered. Furthermore, the difference between the horizontal and the vertical difference histogram...
Regularization plays a vital role in ill-posed problems. A properly chosen regularization can direct the solution toward a better quality outcome. An emerging powerful regularization is one that leans on image examples. In this paper, we propose a novel scheme for face hallucination. We target specially the quality of highly zoomed outputs. Our work bases on the pyramid framework and assigns several...
A stable adaptive fuzzy control method is proposed for multiple-input multiple-output uncertain nonlinear systems. The adaptive law utilizes two types of errors in the adaptive fuzzy systems, the tracking error and approximation error. This control law is applied to a two link robot manipulator, and simulation results show its validity
