Determining images having unidentifiable license plates
First Claim
1. A method of processing an image, the method comprising the steps of:
- a computer determining a category specifying characteristics of a shape of a license plate of a vehicle;
based on the category specifying the characteristics of the shape of the license plate, the computer determining characteristics of objects in the image match the characteristics of the shape of the license plate;
the computer determining the image includes the license plate and an identifier included in the license plate;
the computer determining a category specifying characteristics of an order of alphanumeric characters in the identifier, the order required to be a characteristic of identifiable license plates;
based on the category specifying the characteristics of the order of the alphanumeric characters in the identifier, the computer determining characteristics of the objects in the image do not match the characteristics of the order of the alphanumeric characters in the identifier;
based on the characteristics of the objects in the image not matching the characteristics of the order of the alphanumeric characters in the identifier, the computer determining the image does not include an identifiable license plate; and
in response to the step of determining the image does not include the identifiable license plate, the computer determining the image is invalid and bypassing a manual character recognition process for determining identifiers on license plates.

Abstract
An approach for processing an image is presented. A category specifying characteristics of a shape of a license plate of a vehicle is determined. Characteristics of objects in the image are determined to match the characteristics of the shape. The image is determined to include the license plate and an identifier. A category specifying characteristics of an order of alphanumeric characters in the identifier is determined. Characteristics of the objects in the image are determined to not match the characteristics of the order of the alphanumeric characters in the identifier and based on the lack of a match, the image is determined to not include an identifiable license plate. Responsive to determining the image does not include the identifiable license plate, the image is determined to be invalid and a manual character recognition process for determining identifiers on license plates is bypassed.
