Feature Extraction for image super-resolution using finite rate of innovation principles

Loic Baboulaz, Pier Luigi Dragotti
In the first part, it is shown that the geometric moments of an observed scene can be retrieved exactly from sampled images and used as global features for registration.  ...  : moments and edges.  ...  Using the annihilating filter method, the Radon projections can be reconstructed one by one until there are enough Radon projections to allow the reconstruction of the original 2-D polynomials with convex  ...
