First Claim
Patent Images
1. A method for estimating a resolution of a digital image comprising a digital representation of a document, the method comprising:
- 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 text characters; and
estimating the resolution of the digital image based on the one or more average character dimensions.

Abstract
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.
