摘要
数字视频属于国家重点发展的信息产业领域,宽带网络和数字电视的迅速发展,使得视频点播、交互电视、视频网站等应用都将面临大量涌现的数字化视频数据,对视频摘要技术的研究、对基于视频的各种应用就具有重要意义。文章研究的目的在于通过分析视频中的音频信息,对音频数据先滤波后分析的计算方法,减小了噪音数据对系统判断的影响,提高了准确率,此方法对基于音频分析的其他视频摘要系统的设计提供了相应的参考价值。
Digital video belongs to the field of information industry which the Country develops especially. With the rapid progress of broadband network and digital TV, the applications of video-on-demand, interactive TV and video website become more and more popular. All of these applications are facing the emerging digitalized video data in a large amount. Thess all contribute to the development of digital video processing technologies. Purpose of this study is to analyze audio in a video message, after first filtering calculation method for analysis of audio data, reduces the noise data to judge the impact of the system, improves accuracy, this approach to design of other video summarization system based on audio analysis provides valuable reference.
