Claim Text:
1. A method for automatically recognizing license plate information, the method comprising: receiving an image of a license plate; generating, using one or more processors, a first image processing data set by processing the image using a first set of image processing parameters; generating a first computer-generated score based on the first image processing data set by: determining that the first computer-generated score is: in response to determining that the first computer-generated score is greater than the first threshold score and is less than the second threshold score, determining a second set of image processing parameters based on the first set of image processing parameters; generating a second image processing data set by processing the image using the second set of image processing parameters; generating a second computer-generated score based on the second image processing data set by: determining that the second computer-generated score is greater than the second threshold score; determining that a segment score of a character of the first plurality of characters is greater than a segment score of a corresponding character of the second plurality of characters; and in response to determining the second computer-generated score is greater than the second threshold score and that the segment score of the character of the first plurality of characters is greater than the segment score of the corresponding character of the second plurality of characters, generating license plate data based on the character of the first plurality of characters and the second image processing data set, wherein the character of the first plurality of characters replaces the corresponding character of the second plurality of characters in the license plate data.
