| 摘 要： | 针对数字技术的发展促使个人的多媒体数据资料量越来越大,给人们的使用造成很大的不便,人们迫切需要能对这些资料进行检索和管理的工具,提出了利用相容粗糙集理论对音频数据进行预检索的新方法,即在相容类的近似空间中对音频数据进行预检索.实验结果表明,该方法可以有效地克服等价粗糙集在音频检索方面的限制,对提高检索效率具有一定的作用.

| Abstract: | With the development of digital technology,the volume of personal multimedia archives are made ever-increasing,which brings much inconvenience to the users,so that it is urgent for the user to efficiently index and retrieve the multimedia.A novel method for audio data pre-indexing was presented with the help of compatible rough set,where the audio data were pre-indexed in a compatible-type approximate space.Experimental evaluation showed that the proposed approach could effectively overcome the limitation of equivalent rough set in respect of audio indexing and improve the efficiency of audio indexing to a certain extent. |
