- section Image Analysis
- section Morphometry
- On a 2D image $ OSD = P/T.Ar $
- On a 3D image $ OSD = S/TV $
- $P$ is the object Crofton Perimeter.
- $T.Ar$ is the total area (area of the mask if provided, else area of the image bounding box).
- $S$ is the object surface area calculated using the Area3d algorithm.
- $TV$ is the total volume (volume of the mask if provided, else volume of the image bounding box).

Class Syntax
Parameters
| Class Name | ObjectSurfaceDensity |
|---|
| 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. | ObjectSurfaceDensityMsr | nullptr | |
