摘要

真实彩色视频需要消耗大量的传输带宽和硬件资源。为了适应有限的传输带宽，提出了一种利用彩色分量组合对彩色视频图像进行实时处理的新方法。将视频图像的Y、U、V平面打包成二维复杂数组。通过频域分解，对特定复阵列进行一次傅里叶变换，分别得到Y、U、V频率。这些频率可以被过滤以产生最终的过滤图像。实验结果表明，与传统算法相比，该算法的速度提高了3倍，并减少了1/3的视频数据流带宽。

Color Videos' Multichannel Combination for Bandwidth Reduction and Fast Frequency Domain Processing

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.
