RadialIntensityProfile3d

Computes a radial intensity profile on a 3D image.

Access to parameter description

This algorithm computes an intensity profile that consists in the average intensity at a distance r from a given center.

The output is a 3-column spreadsheet indicating, for each radius, the corresponding average intensity value and standard deviation.
