Morphology-based approach for interslice interpolation of anatomical slices from volumetric images.
npm install @itk-wasm/morphological-contour-interpolationImport:
import {
morphologicalContourInterpolation,
setPipelinesBaseUrl,
getPipelinesBaseUrl,
} from "@itk-wasm/morphological-contour-interpolation"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. |
