Abstract :
In the paper, a new cloud clearing method based on isotherm auto-connection is proposed. The extraction of the isotherm image, the auto-connection of broken-isotherms, and the interpolation-restoration of the temperature are discussed. Some experiments and error analyses demonstrate that this new method can restore and keep the isotherm´s natural shape effectively and the precision of the restored temperature is high enough for sea phenomena analysis
