DSP原理和技术是一门实践性很强的课程，而研究生生源为全国各地，所从事的课题研究又多种多样，因此为了培养和激发学生的创新能力，选择循序渐进的实验教学内容和探索有效的实验教学方法就显得非常重要。作为一种尝试，根据该校拆除教学和科研之间的墙的办学特色，将有关流媒体的部分科研成果应用到教学实践中。 相似文献

This paper proposes a modified shape coding algorthm called modified vertex-based shape coding(MVBSC) to encode the boundary of a visual object compactly by using a modified polygonal approximation approach which uses modified curvature scale space (CSS) theory to extract feature0points. 相似文献

1 Introduction Scalable coding has already been recognized as aneffective solution to resolve the network’s bandwidthvarying[1].It is also i mportant for video transmissionin error-prone environments , congest-prone networkand network with varying quality of service ,such aswireless video transmission systems .So it plays a veryi mportant role in both network communication andwireless communication. MPEG-4 video standard supports fine granularityscalability ( FGS) fine granularity scalabil… 相似文献

One of the most interesting questions of video streaming over the Intemet is packet loss. Some error resilient technologies have been proposed to overcome quality decrease of reconsixucted video occurred due to packet loss, in which optimized reconstructionbased DCT （ORB-DCT） utilizes two-direction interleaving. An improved ORB-DCT （IORB-DCT）, which uses four-direction interleaving, is proposed in this paper. Experimental results are demonstrated to verify the effectiveness of the proposed IORB-DCT. 相似文献
