An Algorithm Research for Compressing the Video and Transmitting Based on the Space Domain

针对不同用户对视频信号分辨率要求的不同,人们提出了许多降低分辨率的算法,其目的都是为了解决视频信号的传输对带宽的占用问题。因此,提高信噪比和降低带宽占用成为焦点。本文在分析了传统降低分辨率算法的基础上,提出了一种新的基于空间域的降低分辨率的改进算法。实验结果表明,本文方法不仅提高了信噪比,降低了带宽的占用,而且恢复之后的图像具有较好的视觉效果。

In order to satisfy different people＇s demands for video resolution,many algorithms have been put forward with the aim to decrease the band-width.Therefore,increasing the signal and noise ratio and decreasing the band-width have attracted much attention.A new improved algorithm for decreasing resolution in space domain is proposed based on the analysis for the conventional algorithm.It is proved that the new algorithm can not only improve the signal-noise ratio and decrease the band-width,but also obtain better optical effect after resuming the video.
