本研究的宗旨在於發展出盲用點字樂譜轉譯程式。使用者可以將所要學習的樂譜先經掃描器轉至電腦檔案中,然後,藉由這個轉譯程式直接轉譯成點字樂譜檔案。之後,可以用盲用點字機顯示或印刷成點字樂譜。如此一來,可大量減少人工製作的費用以及縮短製作時間。本篇論文將僅討論一些重要的前處理過程,譬如五線譜的偵測、音樂符號(Music symbols)的切割及部分音符的辨識。 The purpose of this study is to develop an optical Braille music score translating software. A user can first scan music scores and then run the translating software. The output file can be either output to Braille or to be printed. By using the software, we can greatly reduce the labor fee and shorten the manufacturing time. This paper only discusses some important preprocessing processes (e.g . staff line identification, music symbols segmentation and the recognition of part of music symbols).
