ants.ops.iMath

iMath(image, operation, *args)[source]

Perform various (often mathematical) operations on the input image/s. Additional parameters should be specific for each operation. See the the full iMath in ANTs, on which this function is based.

ANTsR function: iMath

Parameters:

image (ants.core.ANTsImage) – input object, usually antsImage
operation – a string e.g. “GetLargestComponent” … the special case of “GetOperations” or “GetOperationsFull” will return a list of operations and brief description. Some operations may not be valid (WIP), but most are.
*args (non-keyword arguments) – additional parameters specific to the operation

Example

>>> import ants
>>> img = ants.image_read(ants.get_ants_data('r16'))
>>> img2 = ants.iMath(img, 'Canny', 1, 5, 12)
