| Abstract | In this work we describe an implementation of the 2D Tikhonov regularization filter which scales linearly with the input signal's size. We propose a novel algorithm to decompose the filter's 2D kernel as a sum of axis-aligned Gaussians. Our algorithm uses symmetries of the kernel to provide a fast computation of the Gaussian decomposition in the frequency domain, where the 2D Tikhonov kernel has a closed-form expression. The convolution with each Gaussian is then computed using linear-time separable recursive filtering. This way, a fast solution to the 2D Tikhonov regularization problem is obtained. | |||
