Abstract:

By analyzing the iso-flux feature of edge plasma and making use of active contour model, the plasma boundary was re-constructed; the contour energy, the algorithm steps, the method of edge-flux calculation and the method of initial-contour definition were introduced. Compared with EAST experimental data, this method shows a favorable accuracy and high real-time performance.
