 Once a spatial relationship is defined, we create a GLCM of size (Range of Intensities x Range of Intensities) all initialised to `0`. For eg, a `8` bit single channel Image will have a `256x256` GLCM. We then traverse through the image and for every pair of intensities we find for the defined spatial relationship, we increment that cell of the matrix.

 Each entry of the GLCM[i,j] holds the count of the number of times that pair of intensities appears in the image with the defined spatial relationship.

 You can see that classifier gave low score to not-human class (i.e. high score to human class) at positions corresponding to humans in the original image.
