RadialIntensityProfile2d
Computes a radial intensity profile on a 2D 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.
