From monocular photograph to angle lambda: A new clinical approach for quantitative assessment

Angle lambda assessment is essential in pediatric and strabismus practice. An abnormal angle lambda will modify the visual appearance of a strabismus or mimic one. Currently, angle lambda can be assessed by corneal topographs. Unfortunately, the use…

Méthodes d'apprentissage automatique appliquées à l'analyse des signaux d'utilisations des grands calculateurs

The aim of this thesis is to determine what statistical methods can currently be used to improve the understanding of the use of a computing center. We decompose the computer into three parts : hardware, software and users in order to identify three…

Débruitage et dématriçage concret de videos avec des réseaux de neurones

Image denoising is a fundamental task in image processing. The goal of denoising is to recover the underlying signal. Several methods have been proposed. They can be classified in 2: the model-based approaches and the data-driven methods. Model…

Video Signal-Dependent Noise Estimation via Inter-Frame Prediction

We propose a block-based signal-dependent noise estimation method on videos, that leverages inter-frame redundancy to separate noise from signal. Block matching is applied to find block pairs between two consecutive frames with similar signal. Then…

Classification non-supervisée de documents à partir des modèles Transformeurs

Pre-trained Transformer-based word embeddings are now widely used in text mining where they are known to significantly improve supervised tasks such as text classification, named entity recognition and question answering. Since the Transformer…

Demosaicing to Detect Demosaicing and Image Forgeries

The trustfulness of images is a critical concern. Digital photographs can no longer be assumed to be truthful; indeed, digital image editing tools can easily and convincingly alter the semantic content of an image.Being able to analyse an image to…

Bayesian causal network modeling suggests adolescent cannabis use accelerates prefrontal cortical thinning

Abstract While there is substantial evidence that cannabis use is associated with differences in human brain development, most of this evidence is correlational in nature. Bayesian causal network (BCN) modeling attempts to identify probable causal…
