A new step in the automation of Meudon's Synoptic Map of Solar Activity

Thanks to the automatic solar features detection developed in the frame of the European EGSO (European Grid of Solar Observations) project, an important part of the automation of Meudon's Synoptic Maps is achieved. But it is still necessary to work on the tracking of solar structures in time in order to be able to build the synthesis of structures' evolution during a Carrington rotation. A new approach for filaments gives successful results, using a method based on image segmentation and intersection of regions of interest. This is an important steps in order to advance towards a fully automatic building of Meudon's Synoptic Maps of Solar Activity.
