摘要：
A method for adjusting a license plate that is detected in a captured image includes automatically determining at least one set of correction parameters corresponding to a slant-oriented license plate. The method further includes receiving an input image representing a detected license plate. In response to receiving the input image, the method includes automatically adjusting the input image to obtain a corrected image using the at least one set of correction parameters.
