Methods to locate and eliminate the solar specular reflection point in the meteorological satellite images

摘要

In this paper, methods to locate the sunglints from geostationary meteorological satellite images are discussed, and then an algorithm for moving the sunglints from the satellite images is described. Based on the correlation between different channels of the sensor, data from the IR channel which is seldom affected by solar specular reflection is used to correct the grayscale value of the sunglint area in the visible band images. The algorithm for moving the sunglints is tested by using regression method upon the MODIS remote sensing images and proved to be effectual.
