Abstract
A demosaicing method is disclosed as being applied to an initial image in order to obtain a demosaiced image, enabling an improved demosaicing due to the fact that it includes a noise variance stabilization transformation, for each reference patch: a determination of a set of similar patches, a determination of a covariance matrix for said set of similar patches, and for each similar patch, a calculation of estimates of the interpolated spectral bands according to a block-based deconstruction of the covariance matrix as a function of the phasing, a determination of the interpolated spectral bands by an aggregation of estimates of the interpolated spectral bands, and an inverse transformation of the stabilization transformation.
