In brief, the WRP and its extension, the VDP, is a hypothetical plane that is located between the hologram and the object scene, and which is at close proximity to the latter. As such, the fringe patterns on the hypothetical plane are carrying the holistic information of the hologram, as well as the local optical properties of the object scene. This important property enables a hologram to be processed with classical image processing techniques that are normally unsuitable for handling holographic information. In this paper we shall review a number of works, that have been developed based on the framework of the WRP and the VDP.展开更多

The system is divided into two subsystems: agrometeorological disaster subsystem and dis aster reduction strategy subsystem. The agrometeorological disaster subsystem incIudes the whole process of disaster from occurrence, development to extinction. The subsystem of disaster reduction strategy is strategy measures included prevention, resistance and remedy of disaster The system involves monitoring, forecasting, prevention, resistance, control, loss assessment of disaster and efficiency analysis of disaster reduction. Therefore, modern information techniques (remote sensing, artificial intelligence, crop simulation etc. ) are necessary for improving the a bility of prevention and reduction of展开更多
