Methods, systems and processor-readable media for designing a license plate overlay decal having infrared annotation marks
First Claim
1. A method for designing a license plate overlay decal, said method comprising:
- providing an infrared readable annotation mark with respect to a character image associated with a license plate via training of an automatic license plate recognition engine to improve automatic license plate recognition performance; and
rendering a plate overlay decal with said infrared readable annotation mark wherein said infrared readable annotation mark is visible when illuminated by infrared light and said license plate appears normal in visible light.

Abstract
Methods, systems and processor-readable media for providing a license plate overlay decal with an infrared readable annotation mark for an optical character recognition and segmentation. The annotation mark with respect to character image of a license plate can be designed by training an ALPR engine to improve automatic license plate recognition performance. A plate overlay decal can be rendered with the annotation mark and attached to a license plate. The annotation mark can also be directly placed on the license plate when the license plate is rendered. The annotation mark is visible when illuminated by an infrared light and the license plate appears normal in visible light. The annotation mark enables an ALPR imaging system to obtain more information for each character and utilize the information to improve conclusion accuracy.
