美国的一些机场很快将开始使用一种所谓的“反向散射x射线技术”对乘客进行检查。 - With the images gotten from widely used dual - energy x - ray system , this paper puts emphasis on the research of image segmentation in value domain and space domain , and bomb image recognition by computer programming techniques
基于当前在安检中广为应用的双能量x射线技术所得到的双能量x光图像，本文重点研究了图像值域分割，图像空间分割和炸弹图像计算机识别问题。 - At the same time , as more and more radio sources have been set up , electromagnetic pollution in urban area becomes more serious , which is harmful to people ' s healthy and communication system so it is necessary to simulate the electromagnetic propagation in urban area by computer being an approximate hf method in evaluating em scattering ， the complex ray method （ crm ） is valuable in actual applications ， mainly benefited from its simple physical model ， convenient mathematical formulation and computational efficiency , especially with the scenes of scattering from complex objects based on the condition mentioned above , a hybrid ray model of the urban area electromagnetic wave propagation prediction was established with the foundation of ray tracing theory and complex ray theory
复射线技术作为一种求解波场问题的高频近似方法，由于其具有物理模型简单、数学处理方便、计算效率高等优点，在复杂的目标散射特性分析等应用领域中有着重要的应用价值。基于以上的情况，本文在射线追踪理论和复射线理论的基础上，为城区环境建立了混合射线预测模型。本文采用椭圆模型对已有的射线追踪方法进行加速，并将复射线理论应用到城区环境电波传播预测中，提出新的预测方法混合射线方法。
