LocalDensityMap3d
Measures the local density of a three-dimensional binary image within a binary mask.
Access to parameter description
This algorithm computes the density using a region formed by the intersection of a mask image and a user-defined kernel.
Access to parameter description
This algorithm computes the density using a region formed by the intersection of a mask image and a user-defined kernel.
- Pixels are assigned the percentage of pixels with a value of 1 inside this region. These values are expressed in the interval [0, 100].
- Pixels outside of the mask are assigned the value -1.

Class Syntax
Parameters
| Class Name | LocalDensityMap3d |
|---|
| Parameter Name | Description | Type | Supported Values | Default Value | |
|---|---|---|---|---|---|
 |
inputBinaryImage |
The input binary image. | Image | Binary | nullptr |
|
inputMaskImage |
The binary mask image. This image must have same dimensions and type as the main input image. | Image | Binary | nullptr |
|
kernelSize |
The side size in voxels of the cubic kernel. | Vector3i32 | >0 | {3, 3, 3} |
 |
outputImage |
Its dimensions are forced to the same values as the input. Its data type is forced to floating point. | Image | nullptr | |
