On the Real Part of Butterfly Factorizations, with Application to Fast Transforms
Ma{ë}l Chaumette, R{é}mi Gribonval, Elisa Riccietti
Fast transforms such as the Discrete Cosine Transform can be expressed as the real part of a product of complex-valued structured sparse matrices known as Kronecker-sparse factors.…
Multiresolution Block-Coordinate Plug-and-Play Algorithm for Image Reconstruction
Edgar Desainte-Mar{é}ville, Marion Foare, Paulo Gon{\c c}alves +2
Plug-and-Play methods are among the state-of-the-art approaches for image reconstruction, but they do not scale well with the image size. We propose a multiresolution block-coordin…
Multiresolution Adaptive Block-Coordinate Forward-Backward for Image Reconstruction
Edgar Desainte-Maréville, Marion Foare, Paulo Gonçalves +2
Classical first-order optimization methods for imaging inverse problems scale poorly with image resolution. Wavelet based multilevel strategies can accelerate convergence under str…
