例句與用法

Based on such shortcomings in studies on query by humming, we did some work as followed : in the module of building a melody database, reduced the data that needed to be calculated by extracting the repeating patterns in the songs, and proposed an improved repeating-pattern-tree ( rp-tree ) algorithm, with much better performance; in the melody extraction module, firstly extracted the sequence of the pitches, then removed some wrong points and reduced the number of dimensions in sequence of pitches in some way after which a time series of pitches was generated; in the melody matching module, analyzed four familiar errors that occur to the humming and the requirement to the search algorithm, by which we designed a retrieval method of dynamic time warping ( dtw ) algorithm based on n-gram index; implemented a prototype system, and after doing the experiments, we got a top ten hit of 94 %
本文針對(duì)以上哼唱音樂(lè)檢索研究中的不足,進(jìn)行了如下工作:在建立旋律庫(kù)模塊,通過(guò)提取樂(lè)曲的重復(fù)模式來(lái)減少旋律匹配的計(jì)算量,提出了重復(fù)模式樹(repeating-pattern-tree,rp-tree)算法的改進(jìn)算法,大幅度提高了重復(fù)模式提取算法的性能;在連續(xù)哼唱輸入的旋律提取模塊,采用了先提取基頻軌跡,再對(duì)基頻軌跡進(jìn)行去除錯(cuò)誤點(diǎn)以及降維操作的方法,生成了音高時(shí)間序列;在旋律匹配模塊,分析了哼唱輸入可能具有的四種常見(jiàn)錯(cuò)誤以及對(duì)檢索算法的要求,設(shè)計(jì)了基于n-gram索引的動(dòng)態(tài)時(shí)間彎折(dynamictimewarping,dtw)檢索算法;最終實(shí)現(xiàn)了一個(gè)哼唱檢索的原型系統(tǒng),通過(guò)實(shí)驗(yàn),達(dá)到了94%的前十名命中率。
The current studies on query by humming focus on humming in special way and approximate string matching . little attentions are put on humming in continuous way, and even using the continuous input method, the matching is still based on the sequence of pitches which has not been processed first
目前對(duì)哼唱音樂(lè)檢索的研究大多把重點(diǎn)放在特定哼唱輸入方式和字符串之間的模糊匹配上,對(duì)于連續(xù)哼唱輸入方式的研究較少,即使采用了連續(xù)哼唱輸入方式,也是直接提取哼唱輸入的基頻軌跡進(jìn)行匹配,缺少對(duì)基頻軌跡預(yù)處理的研究。
