Patent Images

1. A computer-implemented 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;

    classifying an object depicted in the digital image as a member of a particular object class based at least in part on the comparing;

    determining one or more object features of the object based at least in part on the particular object class; and

    detecting the object within the digital image based on the one or more object features, wherein the detecting comprises directly detecting an object color profile within the digital image rather than detecting a transition from a first color profile to a second color profile.
