PT Unknown AU Albert Gordo Alicia Fornes Ernest Valveny Josep Llados TI A Bag of Notes Approach to Writer Identification in Old Handwritten Music Scores BT 9th IAPR International Workshop on Document Analysis Systems PY 2010 BP 247–254 DI 10.1145/1815330.1815362 AB Determining the authorship of a document, namely writer identification, can be an important source of information for document categorization. Contrary to text documents, the identification of the writer of graphical documents is still a challenge. In this paper we present a robust approach for writer identification in a particular kind of graphical documents, old music scores. This approach adapts the bag of visual terms method for coping with graphic documents. The identification is performed only using the graphical music notation. For this purpose, we generate a graphic vocabulary without recognizing any music symbols, and consequently, avoiding the difficulties in the recognition of hand-drawn symbols in old and degraded documents. The proposed method has been tested on a database of old music scores from the 17th to 19th centuries, achieving very high identification rates. ER
