点运算 meaning in Chinese

point operation

Then it introduces the main algorithms including the construction of elliptic curve , points operating , data types conversions , triple encryption , et al . in the end , the security of the cryptographic system is analyzed
然后给出了该方案所涉及主要操作的算法描述，其中包括椭圆曲线的产生、点运算、数据类型转换、基于cbc的三重加密算法等。
In the phase of image pretreatment , the main jobs of this system includes dot operation , image swell , positive chiasma transform , edge extraction and edge swell , outline track , etc . because the visual system itself is a neural system , systematizer designed in the paper adopts bp neural network to accomplish computer image identification , the system has some advantages over the traditional one , but with the extensive application of bp neural network , the problems existing in bp neural network come forth increasingly
在系统软件设计部分中，首先是对所选零件进行模式识别，包括图像预处理、特征提取和分类器设计三个阶段，其中在图像预处理阶段本系统主要做的工作有：点运算、图像增强、正交变换、边缘提取和边缘增强、轮廓跟踪等。由于视觉系统本身就是一个神经系统，故本文所设计的分类器采用bp神经网络，其具有一些传统技术所没有的优点。
