초록/요약
Due to the development of video sharing platforms, the amount of video uploads is exploding. Such videos often include varioustypes of music, among which cover songs are included. In order to protect the copyright of music, an algorithm to find the originalsong of the cover song is essential. However, it is not easy to find the original song because the cover song is a modification of thecomposition, speed and overall structure of the original song. So far, there is no known effective algorithm for searching the originalsong of the cover song. In this paper, we propose an algorithm for searching the original song of the cover song using the inflectionpoints of the melody line. Inflection points represent the characteristic points of change in the melody sequence. The proposed algorithmcompares the original song and the cover song using the sequence of inflection points for the representative phrase of the original song. Since the characteristics of the representative phrase are used, even if the cover song is a song made by modifying the overall compositionof the song, the algorithm's search performance is excellent. Also, since the proposed algorithm uses only the features of the inflectionpoint sequence, the memory usage is very low. The efficiency of the algorithm was verified through performance evaluation.
