ants.utils.channels

Functions

merge_channels(image_list[, channels_first])	Merge channels of multiple scalar ANTsImage types into one multi-channel ANTsImage
split_channels(image)	Split channels of a multi-channel ANTsImage into a collection of scalar ANTsImage types

merge_channels(image_list, channels_first=False)

Merge channels of multiple scalar ANTsImage types into one multi-channel ANTsImage

ANTsR function: mergeChannels

Parameters:

image_list (list/tuple of ANTsImage types) – scalar images to merge

Return type:

ants.core.ANTsImage

Example

>>> import ants
>>> image = ants.image_read(ants.get_ants_data('r16'))
>>> image2 = ants.image_read(ants.get_ants_data('r16'))
>>> image3 = ants.merge_channels([image,image2])
>>> image3 = ants.merge_channels([image,image2], channels_first=True)
>>> image3.numpy()
>>> image3.components == 2

split_channels(image)

Split channels of a multi-channel ANTsImage into a collection of scalar ANTsImage types

Parameters:

image (ants.core.ANTsImage) – multi-channel image to split

Return type:

list of ANTsImage types

Example

>>> import ants
>>> image = ants.image_read(ants.get_ants_data('r16'), 'float')
>>> image2 = ants.image_read(ants.get_ants_data('r16'), 'float')
>>> imagemerge = ants.merge_channels([image,image2])
>>> imagemerge.components == 2
>>> images_unmerged = ants.split_channels(imagemerge)
>>> len(images_unmerged) == 2
>>> images_unmerged[0].components == 1
