Joint Decomposition using Sparse Approximation in Astronomical Multispectral Images
Telescopes today routinely provide high-resolution multispectral images, i.e. 3D images where the third dimension is the wavelength : each pixel of the multispectral image is a peak (or line) spectrum. Then, the spectrum of galaxies is observed to measure the peak shift due to the Doppler effect and induced by galaxy kinematics. the goal of this thesis is to approximate the emission lines peaks in the the Astonomical images. These peaks evolve slowly between two neighbouring spectra, another challenge goal is to estimate the trajectory made by the peaks in order to decompose the image structures.
