- On a 2D image, it returns the Crofton Perimeter, which is homogeneous to a length (dimensionality 1).
- On a 3D image, it returns the result of the Area3d algorithm, which is homogeneous to a surface (dimensionality 2).

Function Syntax
This function returns the outputMeasurement output parameter.

Class Syntax
Parameters
| Class Name | ObjectBoundaryArea |
|---|
| Parameter Name | Description | Type | Supported Values | Default Value | |
|---|---|---|---|---|---|
 |
inputBinaryImage |
The input binary image. | Image | Binary | nullptr |
|
inputMaskImage |
The binary image defining the volume of interest. The measurement is computed from pixels having a 1 value in this image. If it equals null, the computation is performed from all pixels of the input image. It must have same dimensions as the input image. | Image | Binary | nullptr |
 |
outputMeasurement |
The output measurement result. | ObjectBoundaryAreaMsr | nullptr | |
