| Summary: | 碩士 === 國立臺灣大學 === 工程科學及海洋工程學研究所 === 105 === Online musical performances nowadays are popular as the online platforms, like Youtube or Yoku, are widely used. One specific type of performance among these is the instrument solo. Instruments solo using piano, flute, or guitar are recorded and being uploaded to the internet. Some are made as tutorial videos to teach the audiences to learn by themselves. In this paper we explore the possibility transcribing these tutorial video into readable sheet using current software technologies from signal processing and image processing, brining an improvement to the old-fashioned audio signal converting. The experiment is built upon piano solo-playing, as these kinds of performances can be found commonly on Youtube and are easier to perform the video segmentation. In the experiment the comparison between mutual information converting, the sound and video, and single information converting, which is the sound, are discussed. After the discussion, we come to a conclusion whether the adoption of correlative converting is applicable on the other instruments.
