GLCM_Features1
GLCM_Features1 helps to calculate the features from the different GLCMs
that are input to the function. The GLCMs are stored in a i x j x n
matrix, where n is the number of GLCMs calculated usually due to the
different orientation and displacements used in the algorithm. Usually
the values i and j are equal to NumLevels parameter of the GLCM
computing function graycomatrix(). Note that matlab quantization values
belong to the set {1,..., NumLevels} and not from {0,...,(NumLevels-1)}
