Directions

You can specify directions from 4 directions.

  • East: Direction.EAST

  • South East: Direction.SOUTH_EAST

  • South: Direction.SOUTH

  • South West: Direction.SOUTH_WEST

>>> from glcm_cupy import GLCM, Direction
>>> g = GLCM(directions=(Direction.SOUTH_WEST, Direction.SOUTH))

In a full example:

>>> from glcm_cupy import GLCM, Direction
>>> import numpy as np
>>> from PIL import Image
>>> ar = np.asarray(Image.open("image.jpg"))
>>> g = GLCM(directions=(Direction.SOUTH_WEST, Direction.SOUTH)).run(ar)

Bi-Directionality

This algorithm uses bi-directional algorithm in the kernel. It populates GLCM for I, J and J, I.

Note

This bi-directionality performance cost is negligible as it simply adds the transposed GLCM.
