With the rapid development of Remote Sensing acquisition techniques, there is a need to scale and improve processing tools to cope with the observed increase of both data volume and richness. Among popular techniques in remote sensing, Deep Learning gains increasing interest but depends on the quality of the training data. Therefore, this paper presents recent Deep Learning approaches for fine or...
In this paper we propose a denoising technique based on nonlocal means using an image similarity measure. The idea is to use the SVD-based image quality metric as a measure of neighborhood similarity. This measure is then used in the computation of the spatial Gaussian weighting kernel. We also develop an optimization computation scheme using a parallel architecture in order to accelerate the filtering...
Illegal copying of multimedia files has become a very common practice. Indeed, with the rapid development of means of communication, sharing, copying and illegal downloading have become a very easy handling action, at everybody's reach. The magnitude of this continuously increasing phenomenon may have a significant economic impact since it induces a marked loss on turnover. To cope with this huge...
This paper deals with an experiment which proves that wavelet networks are capable for 3D objects modeling. To prove this, we will propose a new structure of wavelet network founded on several mother wavelets families. This new structure is in some ways similar to the classic wavelet networks but it admits some originality. Actually, wavelet network basically uses dilations and translations versions...
3D shape of face has recently emerged as a major research in face biometrics. However, while it is reputed to be relatively invariant to lighting conditions and pose, one still needs to cope with facial expression variations for a reliable face recognition solution and running time of the matching algorithms for fast identification software. We present in this paper our solutions to overcome these...
Digital watermarks have been proposed in recent literature as a means for copyright protection of multimedia data. In this paper, we investigate the use of intelligent wavelet networks to the image watermarking problem. The host image is transformed to the Discrete Wavelet Transform and a wavelet network is utilized to approach coefficients values and memorize it between the original and watermarked...
A remote lab for electrical engineering experiments has been designed and implemented. This has been intended as a platform that supports existing traditional labs by offering lab experiments that serve some of the student learning outcomes of the program. This offers fully interactive environment to the remote user. A dedicated architecture that meets network security and equipment safety requirements...

Pervasive computing requires that devices must be context-aware in order to provide proactively adapted services to both user and applications according to the current context. Most of the proposed approaches of service adaptation in a pervasive computing system are either not context-aware or based on an inappropriate definition of context. In this paper we propose a context-aware dynamic service...
A wavelets neural network is a hybrid classifier composed of a neuronal contraption and wavelets as functions of activation. Our approach of face recognition is divided in two parts: the training phase and the recognition phase. The first consists in optimizing a wavelets neural network for every training picture face. A new technique of training of these wavelets networks which based on the frames...
The watermarking is a technique that gives protection to multimedia data such as images and video. Actually, their protection from malicious manipulations as unauthorized copying and illegal distribution becomes a necessity. A simple re-used of still images watermarking techniques for video watermarking are not sufficiently efficient. In fact, if the mark is embedded in every frame of the video without...
In this paper, a novel dynamic video watermarking is proposed. It takes full advantage of motion information of video content to guarantee the perceptual invisibility and robustness of the watermark. A major advantage of this technique is that the watermark is no longer at a fixed position on the screen, but moves along with moving coefficients. Embedding and extraction of the watermark are based...
