Methods of Content-Based Image Identification
First Claim
Patent Images
1. A method of identifying one or more image features of an image based on content of the image, comprising:
- receiving an image;
correcting a distortion and a tone of the image;
segmenting the corrected image and extracting the one or more image features;
generating an input image descriptor based on the one or more extracted image features;
matching the input image descriptor with a reference image descriptor; and
performing an action based on the matched reference image descriptor.

Abstract
A method of identifying one or more image features of an image based on content of the image according to one example embodiment includes receiving an image, correcting a distortion and a tone of the image, segmenting the corrected image and extracting the one or more image features, generating an input image descriptor based on the one or more extracted image features, matching the input image descriptor with a reference image descriptor, and performing an action based on the matched reference image descriptor.

15. A method of identifying one or more image features of an image captured by a mobile device based on content of the image, comprising:
-
extracting the one or more image features from the image; generating an input image descriptor based on the one or more extracted image features; selecting a matching reference image descriptor for the input image descriptor from a plurality of reference image descriptors, the matching reference image descriptor having a highest matching score with the input image descriptor of the plurality of reference image descriptors; and performing a predetermined action based on the matching reference image descriptor. - View Dependent Claims (16, 17)

18. A method of identifying one or more image features of an image captured by a mobile device based on content of the image, comprising:
-
extracting the one or more image features from the image; generating an input image descriptor based on the one or more extracted image features; selecting a reference image descriptor from a set of reference image descriptors that matches the input image descriptor; and performing an action based on the matching reference image descriptor, wherein the matching reference image descriptor is selected based on a determined correlation coefficient of the input image descriptor and the matching reference image descriptor from the set of reference image descriptors. - View Dependent Claims (19, 20)
