查询词典 step it

Alternating minimization cost function and maximization poster probability is proposed to restore the blurred image. The method is divided two step, one step is EM step, it is to estimate the PSF by using minimimum-error criteria, the other step is M step, we use MAP criteria to restore the blurred image.

This algorithm lights five pixels in a loop between the coordinate information of line's start and end points. Therefore, the speedof generating of straight line can be accelerated. Compared with the four-step, it is the speed that increased by about 20% while the complexity is almost the same. Meanwhile the five-step still maintains the precise of the traditional line scan conversion algorithm.

该算法过给定的直线的始点和终点，可以一次计算得到并且点亮五个象素点，从而较传统的直线扫描转换算法成倍地提高了直线的生成速度，与著名的"四步法"相比，几乎没有增加复杂性，而速度则提高约20%，同时仍然保持传统直线扫描转换算法的精度。

To verify the validity of realizing the integration under the environment of unified feature product model, a CAPP pre-processor is developed, it reads the data that are produced by CAD feature modelling subsystem from database or selfdefined interface files which refer STEP standard, and according to application demands, transforms the data into the form that CAPP requires. Thus, automatic process planning is realized. It provides a foundation of BITIS's other sub-system integration.

为了验证在统一的特征产品模型环境下实现集成的有效性，开发了一个CAPP的前置处理器，从数据库或参考STEP标准自定义的接口文件中读取CAD特征造型子系统产生的数据，根据应用的要求转换为CAPP规定的格式，从而实现了工艺规程自动编制，为BITIS其它环节的集成提供了基础。⑤。
