%description
Two 'Gray Level Co-occurrence Matrix' ('GLCM') implementations are
included: The first is a fast 'GLCM' feature texture computation based on
'Python' 'Numpy' arrays ('Github' Repository,
<https://github.com/tzm030329/GLCM>). The second is a fast 'GLCM'
'RcppArmadillo' implementation which is parallelized (using 'OpenMP') with
the option to return all 'GLCM' features at once. For more information,
