Hierarchical Bag of Paths for Kernel Based Shape Classification
François-Xavier Dupé, Luc Brun
Graph kernels methods are based on an implicit embedding of graphs within a vector space of large dimension. This implicit embedding allows to apply to graphs methods which where u…

Image Deconvolution Under Poisson Noise Using Sparse Representations and Proximal Thresholding Iteration
François-Xavier Dupé, Jalal Fadili, Jean Luc Starck
We propose an image deconvolution algorithm when the data is contaminated by Poisson noise. The image to restore is assumed to be sparsely represented in a dictionary of waveforms…
