Title:

Promising applications of deep learning in medical image analysis

Abstract:

Quantitative image analysis has deep roots in the usage of positron emission tomography (PET) in clinical and research settings to address a wide variety of diseases. It has been extensively employed to assess molecular and physiological biomarkers in vivo in healthy and disease states, in oncology, cardiology, neurology, and psychiatry. There is also increasing interest in the use of artificial intelligence-based techniques, particularly machine learning and deep learning techniques in a variety of applications to extract quantitative features (radiomics) from PET, including image segmentation and outcome prediction in clinical oncology. These novel techniques are revolutionizing clinical practice and are now offering unique capabilities to the clinical molecular imaging community and biomedical researchers at large. Recently, deep learning algorithms have been widely utilized in various medical image analysis problems owing to the promising results achieved in image reconstruction, segmentation, regression, denoising (low-dose scanning) and radiomics analysis for outcome prediction. This talk also reflects the tremendous increase in interest in medical image analysis using deep learning techniques in the past decade. Novel deep learning techniques are revolutionizing clinical practice and are now offering unique capabilities to the clinical molecular imaging community and biomedical researchers at large. Future opportunities and the challenges facing the adoption of deep learning approaches and their role in molecular imaging research are also addressed.

Title:

Modeling and Artificial Intelligence: a fruitful combination

Abstract:

During the past two decades, Artificial Intelligence (AI) has experienced spectacular successes in a very large variety of domains. AI is now present in everyday life as well as in professional activities. The role of models in these successes is fundamental, especially in the fields of interest of ATSIP: image, speech and signal. This presentation will deal with the three main approaches of AI, i.e., symbolic, neuronal, and statistical with in each case, a focus on the aspects related to models. Practical examples will illustrate the presentation. A major part of AI systems of the three above approaches is learning. The different types of learning will be studied, including the case of end-to-end systems based on convolutional neural nets.

Title:

Dynamical changes within brain networks in Alzheimer Disease

Abstract:

“Healthy” older adults demonstrate motor and cognitive deficits due mainly to the natural progressive brain decline, while elderly individuals afflicted a neurological disease such as Alzheimer’s disease (AD) manifest more pronounced motor and cognitive deficits due exacerbated age-related decrements in addition to the gain of toxic functions. An open question is what are the specific dynamical changes within brain networks that result in the motor and cognitive deficits in AD patients ? To address this question, we propose a framework built upon a biophysically plausible model of brain networks dynamics–a neuron-glia-vascular (NGV) network model–which not only allows to generate biophysically plausible hypotheses of motor and cognitive deficits but also ensures consistence between simulated and real word neuroimaging data including ElectroEncephaloGraphy (EEG) and fMRI data.

I was the co-director of the International Laboratory of Neuroimaging and Modelisation of the INSERM-UPMC and Montreal University until 2015. I am currently Scientific Director, PERFORM Centre and Professor, Department of Electrical and Computer Engineering Faculty of Engineering and Computer Science Concordia University Montreal, QC, Canada. My current research group interests are in human brain computational modelling and functional connectivity analysis using multimodal analysis of electromagnetic and hemodynamic processes in the brain and spinal cord. I developped mathematical models to better understand the mechanisms of brain activity and neurovascular coupling using (BOLD fMRI, MRS, EEG, optical imaging) signals. I proposed macroscopic models of the spatial extent of the anatomical networks and their functional dynamics. The overarching goals of my research program is to address the problem of developing models for the numerical simulation of the humain brain activity and physiopathological neurodegenerative disease through an integrated biomedical approach. .

Title:

Spatial observation of the Earth for climate change monitoring

Abstract:

In the context of strong climate and anthropogenic changes, numerous scientific studies are working on establishing a diagnosis of the evolution of the Earth’s surface. This diagnosis is essentially based on modeling studies of the climate and various processes (water cycle, carbon cycle, etc.), and also through observation. This last component is ensured by numerous in situ networks but above all by the spatial observation of the Earth, provided by multiple satellite sensors which allow spatio-temporal monitoring of different climatic variables. They relate to oceanic and continental surfaces and also the atmosphere. The aim of this conference is to detail the potential of space observation of the Earth, an essential component of monitoring climate change."

Title:

"Sensors, EM modeling, inversion problem and oceanic remote sensing"

Abstract:

A radar (Radio Detection And Ranging) is by definition an apparatus to detect the presence (or absence) of obstacles in a natural environment and to know the distance using radio waves. This property is essentially based on the scattered wave. In conventional radar systems, only the energy scattered by the target is taken into account. Thus, the treatment generally concerns a scalar quantity, but the waves are of vectorial nature. In the detection volume of a radar, we observe the presence of undesirable echoes, resulting from atmospheric disturbances (cloud, rain, snow, ...) or reflections of the waves on the ground or on the sea, these elements come to alter a decision making. For example, a satellite radio link and / or a radio link located near the sea surface has its characteristics deeply affected by the atmospheric propagation and / or the presence of the ocean surface and / or the earth's surface. Indeed, the signal from the direct path will be added a number of signals from multiple paths related to reflections from the objects and / or points of the surface. This results in interference between the direct path and the multiple paths resulting in fluctuations in the amplitude and phase of the resulting signal. These fluctuations are a function of the geometry of the link, its electromagnetic characteristics, as well as the state of the land surface and / or the sea surface that depends on the weather conditions. Electromagnetic modeling and signals polarimetric processing can be implemented to minimize clutter to increase the target / environment contrast. The processed signal is then the diffused vector EM field. One of the specificities of this research is based on the relation between the polarization of transmitted and received waves and the obstacle placed in an illuminated environment. The development, design and implementation of an airborne and / or satellite (monostatic or bistatic) radio link fixed or in motion as a whole, to which we are particularly interested, requires the development of research in several directions, including technological aspects, on algorithmic aspects and on emerging applications (detection, recognition, identification, characterization, remote sensing, etc.). As part of this presentation, we will discuss the following aspects: - Different families of modeling, computation and electromagnetic characterization of the interactions of EM waves with the terrestrial and / or sea surface (observed in monostatic, forward and bistatic propagation, and with particular attention to observations at grazing angles), and a marine surface in the presence of the pollutant, or the breaking waves, or complex targets? - Different simulations will be carried out to evaluate different models and in particular compared to the available measures. - Airborne and satellite links: different areas of application and difficulties, future trends? - Inversion problem for estimating from SAR images, the speed and direction of the wind at over sea surface.
Key words: sensors, radar, environment, propagation, EM wave interaction, radar targets, EM signature, sea and land clutter, radar imagery, inversion, detection, classification, indexing and image search, reconnaissance, remote sensing, ...
