Eliminating the effect of solar eclipse in satellite remotely sensed images

Solar eclipse would result in a shadow on the earth which might be observed by orbiting satellite and shown in a satellite image. Even though this rarely happens, a sequence of images contaminated by solar eclipse has been obtained from a geostationary meteorological satellite. The paper describes how the shadows in the imagery series have been eliminated with image processing technique. A 2D model is designed to simulate the shape and variation of the solar eclipse shadow so that the shadow can be cleared to a certain extent. Cloud tracking and pattern recognition techniques are also applied in verifying the algorithm.
