binary conversion meaning in English

二十进制转换
二进制换算

Binary conversion and slant correction algorithm in preprocessing of license plate recognition
车牌识别预处理中的二值化及倾斜矫正算法
Editing floating - point values can result in minor inaccuracies because of decimal - to - binary conversion of fractional components
编辑浮点值时，由于要将小数部分从十进制转换为二进制，因此所得的结果可能存在微小误差。
To this problem a series of image rectification procedure which utilize geometric rectification theory in vehicle license recognition system are pointed out : we first locate vehicle license and execute the edge detection and binary conversion , then proceed calibration in which we use two calibration scheme looking for control point coordinate , one based on the hough transformation , the other based on image analysis method , and finally realize image correction in geometrical transform and bilinear gray interpolation method
针对此问题本文给出了一套将几何畸变校正技术应用到汽车牌照自动识别系统中的车牌图像校正方法：首先提取牌照信息，并对图像进行边缘检测和二值化的预处理；然后提出了基于hough变换控制点提取和基于图像分析法的控制点提取的两种实时标定方法；最后通过空间坐标变换和灰度插值完成图像的校正。
