Convergence Rate of the Symmetrically Normalized Graph Laplacian
Laurent Jacques
This short note aims at (re)proving that the symmetrically normalized graph Laplacian $L=\Id - D^{-1/2}WD^{-1/2}$ (from a graph defined from a Gaussian weighting kernel on a sample…
Invariant Spectral Hashing of Image Saliency Graph
Maxime Taquet, Laurent Jacques, Christophe De Vleeschouwer +1
Image hashing is the process of associating a short vector of bits to an image. The resulting summaries are useful in many applications including image indexing, image authenticati…
Compressed sensing imaging techniques for radio interferometry
Y. Wiaux, L. Jacques, G. Puy +2
Radio interferometry probes astrophysical signals through incomplete and noisy Fourier measurements. The theory of compressed sensing demonstrates that such measurements may actual…
Fast spin +-2 spherical harmonics transforms and application in cosmology
Y. Wiaux, L. Jacques, P. Vandergheynst
A fast and exact algorithm is developed for the spin +-2 spherical harmonics transforms on equi-angular pixelizations on the sphere. It is based on the Driscoll and Healy fast scal…
Correspondence principle between spherical and Euclidean wavelets
Y. Wiaux, L. Jacques, P. Vandergheynst
Wavelets on the sphere are reintroduced and further developed independently of the original group theoretic formalism, in an equivalent, but more straightforward approach. These de…
