SYSTEMS AND METHODS FOR IMPROVING IMAGE RECOGNITION
First Claim
1. A method of processing data, the method comprising:
- detecting image data comprising an image of a license plate;
examining the image data to localize a region of the license plate within the image;
processing, by a processor, the region of the license plate to determine a set of distortion parameters for the license plate; and
applying the set of distortion parameters to the image data to enhance the image of the license plate.

Abstract
An embodiment generally relates to systems and methods for processing license plate image data. A processing module can receive an image comprising a license plate and, from the image, localize a region of the license plate itself. The license plate region can be extracted and license plate distortion parameters can be inferred. The image can be geometrically corrected using the inferred license plate distortion parameters, and the license plate image can be iteratively sharpened to optimize the quality of the license plate image. Further, processing parameters can be modified and applied to the image data in a feedback-based loop for further optimization.
