- add_boundary_regions(regions, pad_width=3)¶
Add boundary regions on specified faces of an image
regions (ndarray) – An image containing labelled regions, such as a watershed segmentation
pad_width (array_like) – Number of layers to add to the beginning and end of each axis. This argument is handled similarly to the
np.padfunction. A scalar adds the same amount to the beginning and end of each axis. [A, B] adds A to the beginning of each axis and B to the ends. [[A, B], …, [C, D]] adds A to the beginning and B to the end of the first axis, and so on. The default is to add 3 voxels on both ends of each axis. One exception is is [A, B, C] which A to the beginning and end of the first axis, and so on. This extra option is useful for putting 0 on some axes (i.e. [3, 0, 0]).
padded_regions – An image with new regions padded on each side of the specified width.
