TotalImageVolume
Measures the volume of interest of a binary image.
Access to parameter description
For an introduction:
On a 2D image, this measurement is more precisely an area, and has dimension 2. On a 3D image, it corresponds to a volume and has dimension 3.
If no mask is provided, it corresponds to the total volume of the input image. If a mask is provided, it corresponds to the volume of the mask image.

On a 2D image, this measurement is more precisely an area, and has dimension 2. On a 3D image, it corresponds to a volume and has dimension 3.
If no mask is provided, it corresponds to the total volume of the input image. If a mask is provided, it corresponds to the volume of the mask image.
Usage without a mask
- On a 2D image $ TV = gx \times cx \times gy \times cy $
- On a 3D image $ TV = gx \times cx \times gy \times cy \times gy \times cy \times gz \times cz \times gx \times cx \times gz \times cz $
- gx, gy and gz represent the image size in pixel coordinates along the X, Y, and Z axes respectively.
- cx, cy and cz represent the image calibration spacing in world coordinates along the X, Y, and Z axes.
Usage with a mask
- On a 2D image $ TV = Ar(M) $
- On a 3D image $ TV = V(M) $
- $M$ is the binary mask image.
- $Ar$ is the 2D area given by the Area2d algorithm.
- $V$ is the 3D volume given by the IntensityIntegral3d algorithm in the binary case.

Class Syntax
Parameters
| Class Name | TotalImageVolume |
|---|
| Parameter Name | Description | Type | Supported Values | Default Value | |
|---|---|---|---|---|---|
 |
inputImage |
The input image. | Image | Binary, Label, Grayscale or Multispectral | 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. | ImageVolumeMsr | nullptr | |
