行频 meaning in Chinese
line frequency
Examples
- Research on infrared image reconstruction simulation with equal row frequency sampling
等行频采样方式下的红外图像帧重建仿真研究 - Typically caused by distortions to the frequency components below the horizontal line frequency
它沿水平方向逐步扩展,通常是由低于行频的频率畸变造成的。 - The person that pass by the path asks a pedestrian , pedestrian dan yun nods line frequency or prevent a river from 15 north , come 40 on the west battalion cropland
道旁过者问行人，行人但云点行频或从十五北防河，便至四十西营田。 - The second , the main work in the paper is discussed . they are include : the theory and character of electromagnetic leaking from a computer ; the theory of accumulation mean filter and pectination filter ; the analysis of synchronous signal precision , at 10 - 12 second level , for stably intercepting ; the technology requirement of receiver and data acquisition board for clearly displaying the images recovered from the intercepted data
本文从计算机视频电磁泄漏和数字滤波器两方面的基本理论出发，详细论述了计算机视频信息电磁泄漏的原理及特点，指出视频泄漏信息的频谱是以行频为周期的谱线；分析了重加滤波器和梳状滤波器的性能；分析了视频泄漏信息截获的条件；推导出稳定截获视频泄漏信息需要对同步信号的精度控制在皮秒级；论述了清晰再现对接收机和数据采集卡的技术要求。 - Researched four technology of structure conversion about digital video , de - interlaced , frame ratio down or up , row ration down or up , the width and high transforming , implemented lots of corresponding arithmetic of four techniques , motion compensate structure conversion method based on the motion estimating improved the image sequence definition and liquidity degree
4研究了数字视频结构变换的四种技术：去隔行技术，变频技术，行频转换技术，宽高比变换技术。实验验证了大量的相关算法，其中基于运动估计的运动补偿结构转换方法，清晰度和流畅度得到了很大的提高。
