Find Surface Area to Volume¶
Group (Subgroup)¶
Statistics (Morphological)
Description¶
This Filter calculates the ratio of surface area to volume for each Feature in an Image Geometry. First, all the boundary Cells are found for each Feature. Next, the surface area for each face that is in contact with a different Feature is totalled. This number is divided by the volume of each Feature, calculated by taking the number of Cells of each Feature and multiplying by the volume of a Cell.
Note: The surface area will be the surface area of the Cells in contact with the neighboring Feature and will be influenced by the aliasing of the structure. As a result, the surface area to volume will likely be over-estimated with respect to the real Feature.
This filter also optionally calculate the Sphericity of each feature.
Parameters¶
| Name | Type |
|---|---|
| Calculate Sphericity | Boolean |
Required Geometry¶
Image
Required Objects¶
| Kind | Default Name | Type | Component Dimensions | Description |
|---|---|---|---|---|
| Cell Attribute Array | FeatureIds | int32_t | (1) | Specifies to which Feature each Cell belongs |
| Feature Attribute Array | NumCells | int32_t | (1) | Number of Cells that are owned by the Feature. This value does not place any distinction between Cells that may be of a different size |
Created Objects¶
| Kind | Default Name | Type | Component Dimensions | Description |
|---|---|---|---|---|
| Feature Attribute Array | SurfaceAreaVolumeRatio | float | (1) | Ratio of surface area to volume for each Feature. The units are inverse length |
| Feature Attribute Array | Sphericity | float | (1) | The sphericity of each feature |
