Perspective-invariant imaging
This paper proposes a new framework called perspective-equivariant imaging that uses the perspective invariance of images from camera systems to solve ill-posed image reconstruction problems without ground truth data. It is applied to multispectral satellite image pansharpening and outperforms other unsupervised methods, achieving state of the art results.
