%description
Creates superpixels based on input spatial data. This package works on
spatial data with one variable (e.g., continuous raster), many variables
(e.g., RGB rasters), and spatial patterns (e.g., areas in categorical
rasters). It is based on the SLIC algorithm (Achanta et al. (2012)
<doi:10.1109/TPAMI.2012.120>), and readapts it to work with arbitrary
dissimilarity measures.
