| Research Abstract |
In order to extract useful information from satellite imagery obtained by optical sensors, we developed following methods : (1) precise geometric correction using system information and simulated illumination image, (2) correction of atmospheric effects due to spatial deviation such as haze and cirrus cloud, (3) precise illumination correction based on physical models and its simplification for practical use.
