Analysis of masks for compressed acquisitions in variational-based pansharpening

Abstract : —The goal of pansharpening is to generate a fused image having both the high spatial resolution of a panchromatic (PAN) and the high spectral resolution of a multispectral (MS) image. For modern low-cost satellite, we envision a strategy for a compressed acquisition with a matrix of custom sensors, which can be seen mathematically as a linear combination of masked sources. We analyze the effectiveness of different masks, both novel and adapted from the literature, on the quality of a fused product, whose reconstruction is based on a flexible inversion scheme based on a variational approach.
