الملخص EN

In this paper, we describe a technique, which uses an adaptive background learning method to detect the CME (coronal mass ejections) automatically from SOHO/LASCO C2 image sequences.

The method consists of several modules: adaptive background module, candidate CME area detection module, and CME detection module.

The core of the method is based on adaptive background learning, where CMEs are assumed to be a foreground moving object outward as observed in running-difference time series.

Using the static and dynamic features to model the corona observation scene can more accurately describe the complex background.

Moreover, the method can detect the subtle changes in the corona sequences while filtering their noise effectively.

We applied this method to a month of continuous corona images, compared the result with CDAW, CACTus, SEEDS, and CORIMP catalogs and found a good detection rate in the automatic methods.

It detected about 73% of the CMEs listed in the CDAW CME catalog, which is identified by human visual inspection.

Currently, the derived parameters are position angle, angular width, linear velocity, minimum velocity, and maximum velocity of CMES.

Other parameters could also easily be added if needed.
