Book and finger position Scan result
The book fan has been removed and the surrounding black area is reduced to a minimum.
The scan result shows a part of the finger in the lower left corner.
The reason is that the analyzing algorithm detected an area of mixed patterns and colors at
the left border of the image. In this case, it is the register of the catalogue.
The finger at the lower left edge was interpreted as part of the register. For this reason, the
finger removal was not executed.
