ObjectVolume

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

Access to parameter description

For an introduction:

section Image Analysis
section Morphometry

This algorithm measures the total volume

$V$ of binarized objects within the image.

On a 2D image, $V$ corresponds to the 2D area $Ar$ given by the Area2d algorithm and has dimension 2.
On a 3D image, $V$ corresponds to the 3D volume given by the IntensityIntegral3d algorithm in the binary case and has dimension 3.
