A new approach is introduced to process the real color video images in real-time using color components combination to fit to the limited transmission bandwidth. The Y  U  V planes of video images are packed to construct a 2 dimensional complex array. Through the decomposition of frequency domain  the Y  U  V frequency can be got respectively by performing Fourier transform a time on the specific complex array. These frequencies can be filtered to generate the final filtered images. The experiment results show that the proposed algorithm is 3X speed compared to the traditional algorithm  and it reduces 1/3 bandwidth of video data stream. 2010 IEEE.   The Calculation of Cumulative Distribution Function of Water Vapor Using Modified Bandwidth 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 2002, 卷号: 11, 期号: 1, 页码: 16,20 Yuhong Nie; Haigeng Chen 收藏  |  浏览/下载：7/0  |  提交时间：2013/03/12 gas radiation  cumulative distribution function  bandwidth.   长距离Φ-OTDR关键技术研究 学位论文  OAI收割 作者:  王照勇   |  收藏  |  浏览/下载：144/0  |  提交时间：2018/12/26 相位敏感光时域反射计  Φ-OTDR  分布式光纤传感  distributed fiber sensing technology  定量化  quantitative measurement  长距离检测  long-haul monitoring  超高响应带宽  ultra-broad response bandwidth.
