چکیده
In this paper, we introduce and discuss the task of sheet music-audio identification. Given a query consisting of a sequence of bars from a sheet music representation, the task is to find corresponding sections within an audio interpretation of the same piece. Two approaches are proposed: a semi-automatic approach using synchronization and a fully automatic approach using matching techniques. A workflow is described that allows for evaluating the matching approach using the results of the more reliable synchronization approach. This workflow makes it possible to handle even complex queries from orchestral scores. Furthermore, we present an evaluation procedure, where we investigate several matching parameters and tempo estimation strategies. Our experiments have been conducted on a dataset comprising pieces of various instrumentations and complexity.

Automatic Mapping of Scanned Sheet Music to Audio Recordings
Significant digitization efforts have resulted in large multimodal music collections comprising visual (scanned sheet music) as well as acoustic material (audio recordings). In this paper, we present a novel procedure for mapping scanned pages of sheet music to a given collection of audio recordings by identifying musically corresponding audio clips. To this end, both the scanned images as well...
متن کاملAutomated Synchronization of Scanned Sheet Music with Audio Recordings
In this paper, we present a procedure for automatically synchronizing scanned sheet music with a corresponding CD audio recording, where suitable regions (given in pixels) of the scanned digital images are linked to time positions of the audio file. In a first step, we extract note parameters and 2D position information from the scanned images using standard software for optical music recogniti...

متن کاملLyric Extraction and Recognition on Digital Images of Early Music Sources
Optical music recognition (OMR) is one of the most promising tools for generating large-scale, distributable libraries of musical data. Much OMR work has focussed on instrumental music, avoiding a special challenge vocal music poses for OMR: lyric recognition. Lyrics complicate the page layout, making it more difficult to identify the regions of the page that carry musical notation. Furthermore...
متن کاملOCR based post processing of OMR for the recovery of transposing instruments in complex orchestral scores
Given a scanned score page, Optical Music Recognition (OMR) attempts to reconstruct all contained music information. However, the available OMR systems lack the ability to recognize transposition information contained in complex orchestral scores. 1 An additional unsolved OMR problem is the handling of orchestral scores using compressed notation. 2 Here, the information of which instrument has ...
