摘要
对数字视频若干关键技术的新进展进行了综述。文章指出,符合国际标准的视频编码及相关技术依然是研究的热点,新的研究方向包括基于小波/子带变换的视频编码、面向对象的视频编码等的研究;针对IP网络和无线网络的可靠性编码及传输技术是目前视频技术研究的又一重大领域;此外,视频流的分析、图像数据库技术,以及图像、视频的水印技术也极具发展前景。文章最后扼要地介绍了目前视频编码最新的标准JVT H.26L的技术特点和研究进展。
This paper reviews some recent advances in the video techniques such as video coding, video stream analysis, and video stream transportation etc. The survey clearly shows that while the standard compliant video coding is still attractive in application, new direction are wavelet/subband based video coding, and object oriented coding. The study on robust video transmission over IP and wireless network is the most challenging topic and of great importance. Besides, video stream analysis, image database technology and video watermark also possess bright application prospect. The paper also gives a brief introduction on the progresses and technical features of the newest standard H.26L of JVT.
