Abstract

Provided is a method for correcting a note image of a damaged note. In the method, the note image is scanned along horizontal scan lines at regular intervals to detect coordinates of intersections between the horizontal scan lines and left and right edges of the note image, and slopes of sections of the note image divided by the horizontal scan lines are calculated using the intersection coordinates. Horizontal scan lines related to the most frequent slope is selected from the calculated slopes. Horizontal scan lines passing through non-damaged sections of the note image is extracted from the selected horizontal scan lines. An x-axis coordinate of a center point of the non-damaged sections is calculated using coordinates of intersections between the selected horizontal scan lines and left and right edges of the note image. The note image is scanned along vertical scan lines at regular intervals to detect coordinates of intersections between the vertical scan lines and upper and lower edges of the note image. A y-axis coordinate of the center point is calculated using the detected intersection coordinates to determine a coordinate of the center point. An inclined angle of the note image is calculated. The note image is rotated on the center point by the calculated inclined angle in a direction opposite to the inclined direction of the note image to obtain a rotation-corrected note image.
