New "glcm" package for calculating co-occurrence textures now on CRAN
Hi all, I just released the new "glcm" package to CRAN. The glcm package enables calculating image textures derived from grey-level co-occurrence matrices (GLCMs) in R. The underlying texture calculation code is implemented in C++ using RcppArmadillo. I have tested the calculated textures versus other implementations, but let me know if you notice anything unexpected. Also, I just pushed out another package to CRAN that may be of interest to some in this group. The "wrspathrow" package has several functions for working with path and row numbers from the World Reference System (WRS, the system used by NASA for the Landsat satellites). The package supports calculating the path(s) and row(s) needed to cover a given sp or raster object, or, conversely, can calculate the polygon for a given path and row. Cheers, Alex
