Imaging with Kantorovich--Rubinstein Discrepancy
Imaging with Kantorovich--Rubinstein Discrepancy
We propose the use of the Kantorovich--Rubinstein norm from optimal transport in imaging problems. In particular, we discuss a variational regularization model endowed with a Kantorovich--Rubinstein discrepancy term and total variation regularization in the context of image denoising and cartoon-texture decomposition. We point out connections of this approach to several …
