Systems and methods for mobile image capture and processing

摘要

In various embodiments, methods, systems, and computer program products for processing digital images captured by a mobile device are disclosed. Myriad features enable and/or facilitate processing of such digital images using a mobile device that would otherwise be technically impossible or impractical, and furthermore address unique challenges presented by images captured using a camera rather than a traditional flat-bed scanner, paper-feed scanner or multifunction peripheral.

主权项

1. A method for estimating a resolution of a digital image comprising a digital representation of a document, the method comprising, using at least one processor:
detecting a plurality of connected components of a plurality of non-background elements in the digital image; determining a plurality of likely characters based on the plurality of connected components; determining one or more average character dimensions based on the plurality of likely characters; and estimating the resolution of the digital image based on the one or more average character dimensions, and wherein the processor is part of a mobile device, the mobile device having an integrated camera.
