Abstract: A demosaicing method applied to an image having pixels each corresponding to an initial spectral band, to obtain a demosaiced image with several spectral bands having pixels each corresponding to the initial spectral band or to an interpolated spectral band. The method includes: on the basis of reference patches and for each reference patch: a determination of a set of patches similar to the reference patch, a determination of a covariance matrix for |the set of patches, and for each patch, a calculation of estimates of the interpolated spectral bands according to a block-based deconstruction of the covariance matrix, where the deconstruction into four blocks is according to phasing of each patch, and a determination of the interpolated spectral bands by an aggregation of estimates of the interpolated spectral bands, where the estimates of the interpolated spectral bands are aggregated for each pixel.
