Class Syntax
Parameters
| 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 voxels having a value of 1 in this image. If it equals null, the computation is performed from all voxels of the input image. It must have same dimensions as the input image. | Image | Binary | nullptr |
 |
outputMeasurement |
The output measurement result. | ObjectVolumeMsr | nullptr | |
| Parameter Name | Description | Type | Supported Values | Default Value | |
|---|---|---|---|---|---|
|
input_binary_image |

|
input_mask_image |
The binary image defining the volume of interest. The measurement is computed from voxels having a value of 1 in this image. If it equals null, the computation is performed from all voxels of the input image. It must have same dimensions as the input image. | image | Binary | None |
|
output_measurement |
The output measurement result. | ObjectVolumeMsr | None | |
| Parameter Name | Description | Type | Supported Values | Default Value | |
