Arguments:

  • size>0,_regularity>=0,_nb_iterations>0

Description:

Segment selected 2D images with superpixels, using the SLIC algorithm (Simple Linear Iterative Clustering).

Scalar images of increasingly labeled pixels are returned.

Default values:

size=16, regularity=10 and nb_iterations=10.
