Module: Area 3D ()
For an introduction, see section Analysis.
This module calculates the area of the object boundary.
In the continuous case, let x(t), y(t) and z(t) be a parametric representation of the boundary curve X, its area is thus obtained as:
This formula has no obvious discrete equivalent, and is, therefore, mostly useless for our purposes. This module uses "intercepts" to take into account the exposed surface of the outer voxels. The idea being that in the "corners", the contribution of a voxel can vary from 1 to 3 depending on configuration.

Input Image [required]
The image to be analyzed. Supported types include: binary images (Uniform Label Field with 2 labels).
Interpretation
This port specifies whether the input will be interpreted as a 3D volume or a stack of 2D images for processing.
- "3D": the module configuration is set to 3D. The image will be processed as a whole in 3D.
- "XY planes": the module configuration is set to 2D. The image will be processed slice per slice.
