Detection of coronal mass ejections using AdaBoost on grayscale statistic features

Guo, Juan; Zhang, Ling; Yin, Jian-qin +2 more

We present an automatic algorithm to detect coronal mass ejections (CMEs) in Large Angle Spectrometric Coronagraph (LASCO) C2 running difference images. The algorithm includes 3 steps: (1) split the running difference images into blocks according to slice size and analyze the grayscale statistics of the blocks from a set of images with and without…
