Systems and methods for mobile image capture and content processing of driver's licenses
First Claim
1. A computer-implemented method of processing an image, comprising:
- receiving an image captured by a camera included in a mobile device;
performing a shape detection test on the image to produce a first set of coordinates representing a set of edges of the image;
performing an internal feature detection test on the image to produce a second set of coordinates associated with a feature set of the image, wherein the internal feature detection test, comprises;
identifying a photo are within the image,determining an aspect ratio of the photo, anddetermining the type of document associate with the image based at least in part on the aspect ratio;
combining the first set of coordinates and the second set of coordinates to generate a set of adjustment parameters associated with the image;
adjusting the image based at least on the adjustment parameters;
outputting the adjusted image.

Abstract
Systems and methods are provided for processing and extracting content from an image captured using a mobile device. In one embodiment, an image is captured by a mobile device and corrected to improve the quality of the image. The corrected image is then further processed by adjusting the image, identifying the format and layout of the document, binarizing the image and extracting the content using optical character recognition (OCR). Multiple methods of image adjusting may be implemented to accurately assess features of the document, and a secondary layout identification process may be performed to ensure that the content being extracted is properly classified.
