Claim 5:
6. A method of identifying at least a part of a musical character in a digital image of a musical score comprising:
converting the digital image into a matrix in which at least one cell of the matrix corresponds to a pixel of the digital image;
setting the at least one cell of the matrix to a first value if the corresponding pixel of the digital image has a pixel intensity above a threshold intensity;
identifying cells of the matrix corresponding to line pixels, the line pixels corresponding to a line of a stave and/or a stem of a note in the digital image;
identifying a split end of an object in the digital image, wherein the split end comprises cells having the first value and being directly adjacent to those identified as corresponding to line pixels;
adding at least one cell having the first value to the split end of the object to create a repaired object, the repaired object comprising the added at least one cell and the object, the at least one cell being directly adjacent to the split end of the object;
determining a matching value for the repaired object by comparing a characteristic of the repaired object with a characteristic of a representation of at least part of a musical character; and
determining that the repaired object corresponds to the at least part of a musical character if the matching value exceeds a matching threshold.
