Abstract: An image processing system under MS-Windows environment has been developed on micro-computer in order to facilitate the data analyzing of all-sky auroral image recorded in polar region. The system has realized: information extraction of aurora s shape, position, motion and brightness on geomagnetic coordinate. -
