【摘要】 针对现有面向内容音乐信息近似检索算法的弊端,结合递归算法的特点,设计了一则基于递归的面向内容音乐信息近似检索算法;为配合该算法,设计了相应的基于R-tree树的音乐信息索引结构方案;经理论分析和对比实验结果,发现以递归来设计音乐信息近似检索算法,可得到较佳的检索效率。更多还原

【Abstract】 Aiming at the disadvantage of the music-info false-retrieval algorithms based on content retrieval,consulted the characteristics of recursion,designed a recursion-based algorithm in music-info false-retrieval aiming at content.Designed a corresponding R-tree based scheme of music-info index to cooperate with this algorithm.By analyzing theoretically and experiments,it is found that it will get better efficiency by using recursion in designing a music-info false-retrieval algorithms.更多还原
