ImageDev

GeodesicMinima

Extracts the geodesic radius of the particles from a geodesic propagation image.

Access to parameter description

For an introduction: This algorithm is dedicated to be applied on the GeodesicPropagation2d output. It perform a geodesic propagation in one direction only, and extracts the minimum value. It extracts the geodesic radius of the particles.
