To extract some statistical and physical properties of these elements (e.g., filling factors, magnetic flux, size, lifetimes), the Yet Another Feature Tracking Algorithm (YAFTA), a region-based method, is employed. An area with 400$^{\\prime\\prime}\\times$400$^{\\prime\\prime}$ was selected to investigate the magnetic characteristics during the year 2011.
