Abstract :
An automated technique to segment solar coronal loops from intensity images of the sun´s corona is introduced. It exploits physical characteristics of the solar magnetic field to enable robust extraction from noisy images. The technique is a constructive curve detection approach, constrained by collections of estimates of the magnetic field´s orientation. Its effectiveness is evaluated through experiments on synthetic and real coronal images.
