An Algorithm to Extract the Boundary and Center of EUV Solar Image Based on Sobel Operator and FLICM
An algorithm to extract the disk boundary and center of EUV solar image using the Sobel operator, Fuzzy Local Information C-Means Clustering algorithm (FLICM), and the least square circle fitting method is proposed in this paper. The Sobel operator can determine the solar disk boundary preliminarily...
