A multiscale regularized restoration algorithm for XMM-Newton data
H. Bourdin, E. Slezak, A. Bijaoui +1
We introduce a new multiscale restoration algorithm for images with few photons counts and its use for denoising XMM data. We use a thresholding of the wavelet space so as to remov…

A Morphological Indicator for Comparing Simulated Cosmological Scenarios with Observations
E. Lega, A. Bijaoui, J. -M. Alimi +1
We propose a morphological multi-scale analysis of large-scale structures obtained by computer simulations and by observations. Structures are obtained at different scales by apply…
