| Abstract: |
The high spatial and time resolution data obtained by the telescopes aboard Hinode revealed the new
interesting dynamics in solar atmosphere. In order to detect such events and estimate the velocity of
dynamics automatically, we examined the estimation methods of the optical flow based on the OpenCV that is the
computer vision library. We applied the methods to the prominence eruption observed by NoRH, and the polar
X-ray jet observed by XRT. As a result, it is clear that the methods work well for solar images if the images
are optimized for the methods. It indicates that the optical flow estimation methods in the OpenCV library are
very useful to analyze the solar phenomena. |
