Watermarking schemes evaluation Abstract鈥擠igital watermarking has been presented as a solution to copy protection of multimedia objects and dozens of schemes and algorithms have been proposed. Two main problems seriously darken the future of this technology though. Firstly, the large number of attacks and weaknesses which appear as fast as new algorithms are proposed, emphasizes the limits of this technology and in particu-lar the fact that it may not match users expectations. Secondly, the requirements, tools and methodologies to assess the current technologies are almost non-existent. The lack of benchmarking of current algorithms is bla-tant. This confuses rights holders as well as software and hardware manufacturers and prevents them from using the solution appropriate to their needs. Indeed basing long-lived protection schemes on badly tested watermarking technology does not make sense.

Abstract - A ﬂ exible multiscale and directional representation for images is proposed. The scheme combines directional ﬁ lter banks with the Laplacian pyramid to provides a sparse representation for two- dimensional piecewise smooth signals resembling images. The underlying expansion is a frame and can be designed to be a tight frame. Pyramidal directional ﬁ lter banks provide an effective method to implement the digital curvelet transform. The regularity issue of the iterated ﬁ lters in the directional ﬁ lter bank is examined.

Abstract—The contourlet transform is a new two-dimensional extension of the wavelet transform using multiscale and direc- tional ﬁ lter banks. The contourlet expansion is composed of basis images oriented at various directions in multiple scales, with ﬂ exible aspect ratios. Given this rich set of basis images, the contourlet transform effectively captures smooth contours that are the dominant feature in natural images.

Abstract—Stable direct and indirect decentralized adaptive radial basis neural network controllers

Abstract—Stable direct and indirect decentralized adaptive radial basis neural network controllers are presented for a class of interconnected nonlinear systems. The feedback and adaptation mechanisms for each subsystem depend only upon local measurements to provide asymptotic tracking of a reference trajectory. Due to the functional approximation capabilities of radial basis neural networks, the dynamics for each subsystem are not required to be linear in a set of unknown coefﬁ cients as is typically required in decentralized adaptive schemes. In addition, each subsystem is able to adaptively compensate for disturbances and interconnections with unknown bounds.
