Unskewed Image
It's an example of removing the staves on an
unskewed image. That's why the first stage of "setting up" would be
"straighting out" the picture. It is important because a difference of
even 2-3 pixels on the different ends of the line could cause us some
serious problems later on.
Removing the staves could be quite complicated
because while getting rid of the staves one should be careful not remove
all the different musical symbols (look at the picture above). However, no
matter how careful a person may be some damage will be done and after the
staves are gone it will necessary to restore damaged musical symbols.
