Research on Mount Wilson Magnetic Classification Based on Deep Learning

The main flow of the network. The first stage of generating object locations is plotted in blue, which is to find approximate locations and rough sizes of the sunspot groups on the solar full images. The second stage of detecting objects is plotted in orange, which is to further determine the specific locations of the sunspot groups on the basis of the first stage and give the classification and confidence score of the sunspot groups. The third stage of merging detection is plotted in red, which is to merge the detections for eliminating the redundant boxes.
