Abstract
We present in this article a detailed analysis and implementation of the
cartoon+texture decomposition algorithm proposed in [A. Buades, J.L.
Lisani, 'Directional filters for color cartoon + texture image and video
decomposition', Journal of Mathematical Imaging and Vision, 2015]. This
method follows the approach proposed by [A. Buades, T. Le, J-M. Morel,
L. Vese, 'Cartoon+Texture Image Decomposition', IPOL 2011], based on
low/high-pass filtering, but replaces the isotropic filters by a bank of
low-pass directional filters. The cartoon image is obtained by filtering
in the direction that leads to the largest local total variation rate
reduction. This permits to improve the performance of the decomposition
near image discontinuities, where an halo effect was produced by the
previous method.
