        **Slices an image into multiple smaller, square-shaped patches.**

        For overlapping patches, set the stride to a value smaller than the patch size.
        For non-overlapping patches, set the stride to a value identical to the patch size (or larger).
        If the stride is set to a value larger than the patch size, parts of the original image will be skipped.

        Optionally, patches entirely corresponding to image background are discarded.
        To decide whether a patch corresponds to image background, the `homogeneity`_ of its `gray-level co-occurrence matrix`_ is considered.

        .. _homogeneity: https://scikit-image.org/docs/stable/api/skimage.feature.html#skimage.feature.graycoprops
        .. _gray-level co-occurrence matrix: https://scikit-image.org/docs/stable/api/skimage.feature.html#skimage.feature.graycomatrix

        In addition, the number of the remaining patches can be reduced by specifying a maximum number of patches to retain.
        Those will be selected randomly.
