Abstract
A chord information extraction device includes a character group extractor, a determiner and a corrector. The character group extractor extracts a character group corresponding to chord information from score image data representing a music score. The determiner determines whether the character group extracted by the character group extractor follows a predetermined chord notation rule. In a case where the character group extracted by the character group extractor does not follow the chord notation rule, the corrector corrects the extracted character group to follow the chord notation rule.
Claims17
A chord information extraction device comprising:
- a character group extractor configured to extract a character group corresponding to chord information from score image data representing a music score;
- a determiner configured to determine whether the extracted character group follows a chord notation rule;
- and
- a corrector configured to, in a case where the determiner determines that the extracted character group does not follow the chord notation rule, correct the extracted character group such that the corrected extracted character group follows the chord notation rule.
A chord information extraction method comprising:
- extracting a character group corresponding to chord information from score image data representing a music score;
- determining whether the extracted character group follows a chord notation rule;
- and
- correcting, in a case where it is determined that the extracted character group does not follow the chord notation rule, the extracted character group such that the corrected extracted character group follows the chord notation rule.
A non-transitory computer readable medium storing a chord information extraction program that, when executed by a computer, causes the computer to:
- extract a character group corresponding to chord information from score image data representing a music score;
- determine whether the extracted character group follows a chord notation rule;
- and
- correct, in a case where it is determined that the extracted character group does not follow the chord notation rule, the extracted character group such that the corrected extracted character group follows the chord notation rule.
