ObjectBoundaryArea

Measures the surface of objects contained in the volume of interest of a binary image.

Access to parameter description

For an introduction:

section Image Analysis
section Morphometry

This algorithm measures the surface area $S$ of solid objects.

On a 2D image, it returns the Crofton Perimeter, which is homogeneous to a length (dimensionality 1).
On a 3D image, it returns the result of the Area3d algorithm, which is homogeneous to a surface (dimensionality 2).

This algorithm takes into account the input image calibration (spacing) and returns thus results in world coordinates.
