We present a numerical scheme to solve the eikonal equation in a Tilted Transversely Isotropic (TTI) medium. The solution to this equation corresponds to the first arrival time of seismic pressure waves in the high frequency asymptotic regime, whose…

Self-supervision versus synthetic datasets: which is the lesser evil in the context of video denoising?

Supervised training has led to state-of-the-art results in image and video denoising. However, its application to real data is limited since it requires large datasets of noisy-clean pairs that are difficult to obtain. For this reason, networks are…

Monotone discretization of the Monge–Ampère equation of optimal transport

We design a monotone finite difference discretization of the second boundary value problem for the Monge–Ampère equation, whose main application is optimal transport. We prove the existence of solutions to a class of monotone numerical schemes for…

Efficient Graph Convolution for Joint Node Representation Learning and Clustering

Attributed graphs are used to model a wide variety of real-world networks. Recent graph convolutional network-based representation learning methods have set state-of-the-art results on the clustering of attributed graphs. However, these approaches…

An assessment of Multi Object Tracking on low framerate conditions

La performance des méthodes de l'état de l'art en suivi multi-objets est généralement montrée sur des vidéos à fréquence image élevée, où les objets bougent très peu d'une image à l'autre. Il y a cependant des intérêts à travailler dans le cas plus…

Receptor Tyrosine Kinase KIT: A New Look for an Old Receptor

RTK KIT regulates a variety of crucial cellular processes via its cytoplasmic (CD) domain composed of the tyrosine kinase domain crowned by highly flexible domains-juxtamembrane region, kinase insert domain and C-tail, key recruitment regions for…
