	Color videos' multichannel combination for bandwidth reduction and fast frequency domain processing (EI CONFERENCE) 会议论文 OAI收割 2nd International Workshop on Education Technology and Computer Science, ETCS 2010, March 6, 2010 - March 7, 2010, Wuhan, Hubei, China 作者: Li S. 收藏 \| 浏览/下载：19/0 \| 提交时间：2013/03/25 The real color video consumes much transfer bandwidth and the resource of the hardware. 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.
