Fast space-variant elliptical filtering using box splines
Kunal Narayan Chaudhury, Arrate Munoz-Barrutia, Michael Unser
The efficient realization of linear space-variant (non-convolution) filters is a challenging computational problem in image processing. In this paper, we demonstrate that it is pos…
