Capturing the Three-Dimensional Motion of the 16 June 2010 CME in the STEREO-SECCHI Observations using Scene Flow
Abstract
The motion of coronal mass ejections (CMEs) in the heliosphere is governed by the complex interactions of the magnetic field and gas pressure both internal and external to the CME. The two-viewpoint observations of the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instrument suite abroad the Solar TErrestrial RElations Observatory (STEREO) mission is a unique resource for studying these forces throughout the heliosphere. To access the fullest potential of these data, we first need to apply advanced image analysis tools to deal with the three-dimensional data. Here, we present the application of the computer vision technique of scene flow on the CME observed by SECCHI on 10 June 2010. Scene flow methods estimate the three-dimensional motion of points in the field of view using multiple camera sequences. We use a scene flow algorithm to estimate the three-dimensional velocity at every point on a surface of the 10 June 2010 CME. We discuss how these technique can be used in future research.
