SSIMmap: The Structural Similarity Index Measure for Maps
Computes the Structural Similarity Index Measure (SSIM) and its
components for raster images and irregular polygon maps. The raster method
follows Wang et al. (2004) <doi:10.1109/TIP.2003.819861>. The polygon method
uses geographically weighted summary statistics described by Brunsdon et al.
(2002) <doi:10.1016/S0198-9715(01)00009-6> with an adaptive nearest-neighbor
kernel. Provides bandwidth selection, value transformations, permutation-based
inference, Fire Weather Index rasters, and Toronto census-derived example data.
