ADOPT: Analytical Demodulation of Periodic Textures for In-Plane Wave Tracking
Jalal Jouidi, Florent Chatelain, Lucie Bailly +3
This paper addresses the problem of tracking in-plane waves from image sequences using periodic surface patterns. Wave-induced deformation is modeled as a spatial phase modulation…

Asymptotic Gaussian Fluctuations of Eigenvectors in Spectral Clustering
Hugo Lebeau, Florent Chatelain, Romain Couillet
The performance of spectral clustering relies on the fluctuations of the entries of the eigenvectors of a similarity matrix, which has been left uncharacterized until now. In this…
