First Claim
Patent Images
1. A method, comprising:
- receiving a digital image captured by a mobile device; and
using a processor of the mobile device;
generating a first representation of the digital image, the first representation being characterized by a reduced resolution;
generating a first feature vector based on the first representation;
comparing the first feature vector to a plurality of reference feature matrices; and
classifying an object depicted in the digital image as a member of a particular object class based at least in part on the comparing.

Abstract
In one embodiment, a method includes receiving a digital image captured by a mobile device; and using a processor of the mobile device: generating a first representation of the digital image, the first representation being characterized by a reduced resolution; generating a first feature vector based on the first representation; comparing the first feature vector to a plurality of reference feature matrices; and classifying an object depicted in the digital image as a member of a particular object class based at least in part on the comparing.

19. A method, comprising:
-
generating a first feature vector based on a digital image captured by a mobile device; comparing the first feature vector to a plurality of reference feature matrices; classifying an object depicted in the digital image as a member of a particular object class based at least in part on the comparing; and determining one or more object features of the object based at least in part on the particular object class; and performing at least one processing operation using a processor of a mobile device, the at least one processing operation selected from a group consisting of; detecting the object depicted in the digital image based at least in part on the one or more object features; rectangularizing the object depicted in the digital image based at least in part on the one or more object features; cropping the digital image based at least in part on the one or more object features; and binarizing the digital image based at least in part on the one or more object features. - View Dependent Claims (20, 21, 22)

23. A system, comprising:
-
a processor; and logic in and/or executable by the processor to cause the processor to; generate a first representation of a digital image captured by a mobile device; generate a first feature vector based on the first representation; compare the first feature vector to a plurality of reference feature matrices; and classify an object depicted in the digital image as a member of a particular object class based at least in part on the comparison.
