Abstract:   
Nowadays, more and more digital images are being sent over computer networks. The works presented in this tutorial show how encryption algorithms provide security to medical imagery. The main objective is to guarantee the protection of medical images during transmission, and also once this digital data is archived. The subsequent challenge is to ensure that such coding withstands severe treatment such as compression. When a physician receives a visit from a patient, he often requires a specialist opinion before giving a diagnosis. One possible solution is to send images of the patient, along with a specialist report, over a computer network. Nevertheless, computer networks are complex and espionage is a potential risk. We are therefore faced with a real security problem when sending data. For ethical reasons, medical imagery cannot be sent when such a risk is present, and has to be better protected. Encryption is the best form of protection in cases such as this. Many different techniques for the encryption of text already exist. In this tutorial we will show how essential it is to ensure the security of medical imagery and data. In a first time we will present the standard encryption algorithms and will show, in a second time, how these can be suited to medical imagery.

Title : The Local Binary Pattern Approach and its Applications to Face Analysis.

Author : Dr. Abdenour Hadid, Machine Vision Group Dept. of Electrical and Information Engineering, University of Oulu, Finland.

Abstract:  
The LBP operator is defined as a gray-scale invariant texture measure, derived from a general definition of texture in a local neighborhood. Due to its discriminative power and computational simplicity, the LBP texture operator has become a popular approach in various applications, including visual inspection, image retrieval, remote sensing, biomedical image analysis, motion analysis, environment modelling, and outdoor scene analysis. Recent developments showed that the local binary pattern (LBP) texture method also provides outstanding results in representing and analyzing faces in both still images and video sequences. This tutorial presents an overview of the LBP approach and its applications to face analysis. First the theoretical foundations of the method are presented. An overview of applying LBP to various face analysis related tasks is then given, including face recognition, face detection, facial expression recognition, visual-speech recognition and gender classification. Extensions to non-face related applications will also be presented. Finally, directions for future research will be discussed. This tutorial can be seen as an extension to our previous tutorials given at ICPR 2006 (Local Binary Pattern Approach to Computer Vision) and at SCIA 2005 (Texture analysis with local binary patterns: theory and applications).

Title : Multichannel image denoising in the wavelet transform domain.

Authors : Pr. A. Benazza, C. Chaux, J.-C. Pesquet, Ecole Supérieure des Communications de Tunis (SUP’COM), Tunisia.

Abstract:   
Multichannel imaging systems provide several observations of the same scene which are often corrupted by additive noise and blurred. In this talk, we are interested both in multicomponent image denoising based on a multiscale representation of the image. We firstly review the most conventional wavelet-based denoising methods. Then, we describe the multivariate statistical approach we adopt in order to exploit the correlations existing between the different wavelet subbands. More precisely, we propose a parametric new estimator that includes, in a unifying framework, many reported denoising methods. The derivation of the optimal parameters is achieved by applying the Stein’s principle in the multivariate case. Experiments performed on multispectral remote sensing images clearly indicate the outperformance of our method with the conventional wavelet techniques.

Title :      Artificial Neural Networks Based Image Processing & Pattern Recognition: From Concepts to Real-World Applications.
Author :   Pr. Kurosh MADANI, University of Paris 12, France.
e-mail :    madani@univ-paris12.fr
Abstract:   
Inspired from biological nervous systems and brain structure, Artificial Neural Networks (ANN) have been, over the recent decades, central sources of inspiration for a large number of original techniques covering a vast field of applications. From a general point of view, ANN could be seen as information processing systems taking advantage from learning and generalization capabilities, making these techniques and the issued systems adaptive. Especially, as a result of their adaptability, ANN represent powerful solutions for image processing, pattern recognition and related problems which became during the last decades central points of an ever-increasing range of real-world and industrial applications. Moreover, these solutions may take advantage from the power issued from the high degree of parallelism provided, on the one hand by image’s parallel nature, and on the other hand, by parallel hardware implementation of ANN. The main goal of this tutorial is to present Artificial Neural Network potential, through main ANN models and based techniques, to solve real world industrial problems dealing with Image processing and pattern recognition fields.
