摘要: |
在多媒体会议系统中, 同时显示多方会议参加者的动态图像, 是提高现有的多媒体会议系统性能的重要方向之一。本文全面地讨论了多个视频图像的组合方式、策略和方法, 提出了视频图像重迭级的概念和按视频图像重迭级组合图像的算法, 从网络传输数据量和图像组合工作量两方面, 分析比较了各种图像组合方式的性能。 |

Abstract: |
In multipart multimedia conferences, each participant may desire to view all of the other participants and other contributed images and video streams or subset of them. And so video composing is an important research topic. This paper discusses combining modes and combining strategies and combining methods of video images. Combining algorithms of video images are given based on relay level of video images. The performance of three combining modes is analysed and compared as well. |
Keywords: multimedia conference system, video image, image relay, image composition |
