Automatic annotation of anatomical structures can help simplify work-flow during interventions in numerous clinical applications but usually involves a large amount of annotated data. The complexity of the labeling task, together with the lack of representative data, slows down the development of robust solutions. In this paper, we propose a soluti...
Dans un contexte de changement climatique et d’érosion de la biodiversité marine, la surveillance écologique des habitats marins les plus sensibles est primordiale et nécessite des méthodes opérationnelles de suivi permettant aux décideurs et gestionnaires d’établir des mesures de conservation pertinentes et d’évaluer leur efficacité. TEMPO et RECO...
Purpose: To propose an optimal multiple motion encoding (OMME) method for Phase-Contrast MRI (PC-MRI) with application to Magnetic Resonance Elastography (MRE) for reconstructing wrap-free wave images. Theory: OMME is formulated and analyzed as an extension of [5] using an arbitrary number of measurements with different motion encoding gradients (M...
Dans cet article, nous nous attachons à reconstruire en 3D un objet opaque plongé dans un milieu réfringent. Plus précisément, le cas qui nous intéresse est celui d'un in-secte piégé dans l'ambre. Cette matière, certes transpa-rente, est colorée et réfringente, ce qui provoque des dis-torsions dans les images. Dans un tel cas de figure, l'esti-mati...
The possibilities of use of urban objects spectral library as an important component of city’s knowledge database are extensive. They are used for the recognition, characterisation and identification of the urban objects and spaces in different towns. But their geographic accuracy is dependent on the study’s area, and possibilities of using in anot...
Lossy compression algorithms trade bits for quality, aiming at reducing as much as possible the bitrate needed to represent the original source (or set of sources), while preserving the source quality. In this letter, we propose a novel paradigm of compression algorithms, aimed at minimizing the information loss perceived by the final user instead ...
In real world applications, the performances of speaker identification systems degrade due to the reduction of both the amount and the quality of speech utterance. For that particular purpose, we propose a speaker identification system where short utterances with few training examples are used for person identification. Therefore, only a very small...
Speckle reduction is a longstanding topic in synthetic aperture radar (SAR) images. Many different schemes have been proposed for the restoration of intensity SAR images. Among the different possible approaches, methods based on convolutional neural networks (CNNs) have recently shown to reach state-of-the-art performance for SAR image restoration....
Equirectangular projection is commonly used to map 360°captures into planar representation, so that existent processing methods can be directly applied to such content. Such format introduces stitching distortions that could impact the efficiency of further processing such as camera pose estimation , 3D point localization and depth estimation. Inde...
