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.   复变换域可视化与语音信号小波全息谱研究 学位论文  OAI收割 工学博士, 中国科学院自动化研究所: 中国科学院自动化研究所, 1998 作者:  郑义 收藏  |  浏览/下载：55/0  |  提交时间：2015/09/02 复变换域  可视化  伪彩色编码  全息声谱  小波变换  相位谱  幅度谱  语音处理  图象处理  z变换  傅里叶变换  Complex transform domain  visualization  pseudo-color encoding  holo-spectrogram  wavelets transform  phase spectrogram  magnitude spe
