gf_decompose

Scale-space decomposition by the guided filter

You can apply image processing effects that modifies the perceived material properties of objects
in photos, such as gloss, smoothness, and blemishes. This is an implementation of the algorithm proposed by
Boyadzhiev et al. (2015) "Band-Sifting Decomposition for Image Based Material Editing".
Documentation and practical tips of the package is available at <https://github.com/tsuda16k/materialmodifier>.

<dt>logspace</dt>
<dd>If TRUE (default), image processing is done in the log space. If FALSE,
computation is performed without log transformation.</dd></dl>
