The Inpainting of Hyperspectral Images: A Survey and Adaptation to Hyperspectral Data

In this work, we survey image reconstruction methods for hyperspectral imagery. First, are view of image interpolation methods, both linear and nonlinear, is given. Second, image inpainting methods, especially from the variational perspective, are analyzed with respect to their suitability for hyperspectral inpainting. The ability to connect edges through occlusions and the structure of the space in which the hyperspectral data lies are especially considered when propagating data into unknown regions. Finally, a general method for adapting image reconstruction methods to the hyperspectral case is presented.
