NIFTI-Processing-rs

This library is designed as an extension of the NIFTI-rs library, adding 3D resampling support. This library is closely modeled after the NiBabel processing module, hence the name.

Features

The resample_to_output and resample_from_to functions with nearest neighbor and trilinear resampling are implemented.

Limitations

• Minimal error checking; Will be extended.

• Minimal unit tests; Will be extended.

• Please also consult the issue tracker.

Requirements

The nalgebra_affine and ndarray_volumes features of NIFTI-rs are required.

Example

Load a Nifti image file with NIFTI-rs and resample the volume to a grid spacing of 1 mm:

use nifti::{NiftiObject, ReaderOptions, NiftiVolume};
use use nifti_processing::{resample_to_output, sampler};

let obj = ReaderOptions::new().read_file("myvolume.nii.gz")?;
let header = obj.header();
let affine = header.get_affine();
let volume = obj.volume();
let im = volume.into_ndarray::<f32>()?;

let nn = sampler::NearestNeighbor::default();
let (resampled_im, resampled_affine) = resample_to_output(&im, &affine, &[1.0,1.0,1.0], nn)
