song list extraction method based on morphological method

The invention relates to a song list extraction method based on a morphological method, which comprises the following steps of: (1) detecting text lines appearing in a song list screenshot by adopting a character detection module, and transmitting the positions of all the text lines to a next region filtering module; (2) filtering out text regions which do not meet requirements by adopting a region filtering module, and reserving real song content information; (3) combining different text lines with the incidence relation by adopting a region combining module so as to integrate richer song information; and (4) carrying out final information extraction by adopting an information extraction module, and filtering again according to the merged region to obtain real song item information. According to the invention, characters which do not belong to song list information can be deleted; different types of information belonging to the same song can be integrated, and the retrieval efficiency is improved.
