A data flow diagram (DFD) diagrams the processes that change data into information.
数据流程图绘制出把数据变成信息的过程。
Study on mathematic model of CAD/DFD information mapping and its realization method;
源模型和目标模型描述之间的异构性是实现模型映射的主要困难。
Therefore, in this paper, a novel Depth from Defocus (DFD) method is proposed to solve this problem.
因此,提出了一种新的通过物距变化恢复景物全局深度信息的方法。
This is the exact opposite of DFD, which is an upward generation of object code from only the database.
这是DFD的,这是一个对象的代码从数据库中只有向上的一代正好相反。
This technique is the easiest to perfect but has never produced like the DFD or the downstream retrieve.
这种技巧是最容易达至完美,但其中鱼率远不及DFD或下游检索。
