Morphology-based approach for interslice interpolation of anatomical slices from volumetric images.

Installation

npm install @itk-wasm/morphological-contour-interpolation

Usage

Browser interface

Import:

import {
  morphologicalContourInterpolation,
  setPipelinesBaseUrl,
  getPipelinesBaseUrl,
} from "@itk-wasm/morphological-contour-interpolation"

morphologicalContourInterpolation

Interpolates contours between slices.

async function morphologicalContourInterpolation(
  inputImage: Image,
  options: MorphologicalContourInterpolationOptions = {}
) : Promise<MorphologicalContourInterpolationResult>

Parameter	Type	Description
`inputImage`	Image	The input image

MorphologicalContourInterpolationOptions interface:

Property	Type	Description
`label`	number	The label to interpolate. Interpolates all labels if set to 0 (default).
`axis`	number	Interpolate only along this axis. Interpolates along all axes if set to -1 (default).
`noHeuristicAlignment`	boolean	Heuristic alignment of regions for interpolation is faster than optimal alignment.
`noUseDistanceTransform`	boolean	Using distance transform instead of repeated dilations to calculate the median contour is slightly faster, but produces lower quality interpolations.
`useCustomSlicePositions`	boolean	Use custom slice positions (not slice auto-detection).
`noUseExtrapolation`	boolean	Perform extrapolation for branch extremities. Branch extremities are defined as regions having no overlap with any region in the next slice. Extrapolation helps generate smooth surface closings.
`useBallStructuringElement`	boolean	Use ball instead of default cross structuring element for repeated dilations.
`labeledSliceIndicesAxis`	number	Axis along which the labeled slice indices are defined. Default is -1 (that is, auto-detection).
`labeledSliceIndicesLabel`	number	Label of the slice indices. Default is 1.
`labeledSliceIndices`	number[]	List of labeled slice indices. Default is empty.
`webWorker`	null or Worker or boolean	WebWorker for computation. Set to null to create a new worker. Or, pass an existing worker. Or, set to `false` to run in the current thread / worker.
`noCopy`	boolean	When SharedArrayBuffer's are not available, do not copy inputs.

MorphologicalContourInterpolationResult interface:

Property	Type	Description
`outputImage`	Image	The output image
`webWorker`	Worker	WebWorker used for computation.

setPipelinesBaseUrl

Set base URL for WebAssembly assets when vendored.

function setPipelinesBaseUrl(
  baseUrl: string | URL
) : void

getPipelinesBaseUrl

Get base URL for WebAssembly assets when vendored.

function getPipelinesBaseUrl() : string | URL
