The author first introduces several problems that interlaced video suffers from : the basic vertical resolution is inadequate for displaying filmlike quality , and interlaced video generates visual artifacts , including edge flicker , shimmering , and diagonal jaggedness . then the author reviews some representative de - interlacing algorithm that has been proposed 论文首先介绍了隔行电视存在的若干个缺陷:对于显示类似于电影质量的图像而言,隔行电视的基本垂直分辨率是不够的;隔行电视还会产生许多视觉虚像,例如边沿闪烁、爬行和锯齿等,接着简单回顾了学术界已经提出的经典的去隔行技术。
In the light of the pulse width of the radar wave , this paper deals with the difference and the relationship between the vertical resolution and the transverse resolution of the ground - penetrating radar , indicates the influence of the noise upon the resolution and , with practical examples , points out that the digital handling of the signal can greatly improve the resolution of the radar 摘要从雷达波脉冲宽度出发,阐述垂直分辨率与横向分辨率的区别和相互关系,并同时指出噪音对分辨率的影响,用实例说明讯号的数字处理能大大的改善分辨率。
This technique can measure the profiles of meteorological fields of the neutral atmosphere and the electron densities of the ionosphere with high precision and high vertical resolutions . it can operate all - weather with long - term stabilities and global coverage . the global - distributed occultation data will have a huge promotion on the numerical weather prediction , climate and space weather researches 该技术可测量自地面到约800km高空的中性大气气象场和电离层电子密度剖面,具有全天候、长期稳定、高精度和高垂直分辨率等特点;该技术提供全球分布的资料,将对数值天气预报、气候研究和空间环境研究起极大的推动作用,在气象、空间、天文以及国防领域具有广泛的应用前景。
Typical output horizontal formats are high definition 1920 pixels and standard definition 1280 pixels . the purpose of the horizontal format conversion is to allow up or down sampling of picture data in order to increase or decrease the number of horizontal samples in a line to allow the video output to match many different standards 水平格式变换的目的在于对视频数据进行上抽样或下抽样以增加或减少每行的像素数量,使视频输出符合不同的标准;垂直格式变换则是对视频图像的垂直分辨率上进行上抽样或下抽样。
