  • Patent number: 12259521
    Abstract: Provided are a method and system of analyzing ingredients of an artificial rainfall for verification of a cloud seeding effect. As the method and system, which can verify an effect of the artificial rainfall in such a manner that a seeding material becomes different according to each temperature of clouds at a seeding altitude, water sampling from precipitation is performed before and after seeding, and thus the ingredients of a water sample are analyzed using each of a method of analyzing a heavy metal component and a method of analyzing a water-soluble ion component according to a cool cloud and a warm cloud so that whether or not there is a change in each concentration of the ingredients can be determined, are provided, an experiment for the artificial rainfall can more effectively be performed.

  • Patent number: 9826162
    Abstract: A method and an apparatus for restoring a motion blurred image are disclosed. The method of restoring a motion blurred image comprises calculating a motion trajectory and a project trajectory of a camera using an embedded sensor; estimating a point spread function according to camera motion by using the motion trajectory and the project trajectory; and restoring the motion blurred image using the estimated point spread function and a spatially variant activity map.
