ants.ops.smooth_image

smooth_image(image, sigma, sigma_in_physical_coordinates=True, FWHM=False, max_kernel_width=32)[source]

Smooth an image

ANTsR function: smoothImage

Parameters:

  • image – Image to smooth

  • sigma – Smoothing factor. Can be scalar, in which case the same sigma is applied to each dimension, or a vector of length dim(inimage) to specify a unique smoothness for each dimension.

  • sigma_in_physical_coordinates (bool) – If true, the smoothing factor is in millimeters; if false, it is in pixels.

  • FWHM (bool) – If true, sigma is interpreted as the full-width-half-max (FWHM) of the filter, not the sigma of a Gaussian kernel.

  • max_kernel_width (scalar) – Maximum kernel width

Return type:

ants.core.ANTsImage

Example

>>> import ants
>>> image = ants.image_read( ants.get_ants_data('r16'))
>>> simage = ants.smooth_image(image, (1.2,1.5))
