Check-in note values can be up to 2gb 簽入說明值的最大大小為2gb。
note values in traditional tonal music are represented by symbols of various kinds, which indicate relative duration . these symbols include note heads, with the necessary stems and flags or beams 固定音值在傳統(tǒng)調(diào)性音樂中用不同的標(biāo)識(shí)來表示相對(duì)時(shí)值。這些標(biāo)識(shí)包括符頭,符干,符尾或連音線。
In this diploma thesis, the statistic and structural characteristic of musical score image is analyzed and synthesized by relevant technology of image project, pattern recognition, mathematical morphology, software engineering, music knowledge, midi and so on . the concept of direction number has been defined, and then the mathematical morphology theory is used to process musical score image and recognize musical information . specialized direction number algorithms are firstly used to preprocess a musical score image and then recognize stafflines, barlines, pitch, note values, clef, etc . finally the musical information of the musical score image is automatically stored in the midi format 本文利用圖像處理、模式識(shí)別、數(shù)學(xué)形態(tài)學(xué)、音樂知識(shí)庫(kù)與midi等相關(guān)技術(shù),分析與綜合數(shù)字樂譜圖像的統(tǒng)計(jì)與結(jié)構(gòu)特征,提出了方向數(shù)等概念,對(duì)樂譜圖像進(jìn)行處理,利用直方圖技術(shù)與方向數(shù)算法識(shí)別譜線、小節(jié)線、符干等樂譜的主要框架,然后用數(shù)學(xué)形態(tài)學(xué)理論識(shí)別音高與時(shí)值,最后根據(jù)這些音樂信息,組合成音樂樂譜信息,并自動(dòng)轉(zhuǎn)化成midi格式。
