Tardon lorenzo@ Received 30 January 2009 Revised 1 July 2009 Accepted 18 November 2009 Recommended by Anna Tonazzini An Optical Music Recognition OMR system especially adapted for handwritten musical scores of the XVII-th and the early XVIII-th centuries written in white mensural notation is presented. The system performs a complete sequence of analysis stages the input is the RGB image of the score to be analyzed and after a preprocessing that returns a black and white image with corrected rotation the staves are processed to return a score without staff lines then a music symbol processing stage isolates the music symbols contained in the score and finally the classification process starts to obtain the transcription in a suitable electronic format so that it can be stored or played. This work will help to preserve our cultural heritage keeping the musical information of the scores in a digital format that also gives the possibility to perform and distribute the original music contained in those scores.
