Fusion of hyperspectral and multispectral infrared astronomical images
2019
In this contribution, we introduce a multispectral and hyper-spectral image fusion method in an astrophysical observation context. Wedefine an observation forward model and solve a approximate regularizedinverse problem in the Fourier domain by a conjugate gradient algorithm.The fusion model is evaluated on simulated observations of the OrionBar by the NIRCam imager and the NIRSpec spectrometer, embeddedon the James Webb Space Telescope.
