medpy.features.intensity.mask_distance(image, voxelspacing=None, mask=slice(None, None, None))[source]#

Computes the distance of each point under the mask to the mask border taking the voxel-spacing into account.

Note that this feature is independent of the actual image content, but depends solely the mask image. Therefore always a one-dimensional feature is returned, even if a multi-spectral image has been supplied.

If no mask has been supplied, the distances to the image borders are returned.

Parameters:
imagearray_like or list/tuple of array_like

A single image or a list/tuple of images (for multi-spectral case).

voxelspacingsequence of floats

The side-length of each voxel.

maskarray_like

A binary mask for the image.

Returns:
mask_distancendarray

Each voxels distance to the mask borders.
