Methods for using extracted features to perform an action
First Claim
1. A method comprising:
- (a) receiving, at a computer system from a user electronic device, a query related to one or more frames from a video signal displayed at the user electronic device;
(b) extracting, using the computer system, one or more features of the one or more frames, wherein the extracted features include a compact representation of at least a portion of the one or more frames related to one or more blocks of pixels of the frame;
(c) identifying, using the computer system, one or more annotations associated with the one or more frames;
(d) identifying, at the computer system, one or more images related to the one or more frames by comparing the extracted features from the one or more frames with reference features from a first plurality of reference works using a sub-linear search of reference features that identifies one or more matches to the one or more frames but does not guarantee to identify an exact match to the one or more frames, wherein the first plurality of reference works are organized using a clustering technique based on annotations including the one or more annotations to eliminate a second plurality of reference works from being searched;
(e) providing, by the computer system to the user electronic device, the identified one or more images along with action information associated with the identified one or more images, wherein the action information is related to an action to be performed at the user electronic device;
(f) receiving, at the computer system from the user electronic device, a selection of one of the identified one or more images; and
(g) providing, to the electronic device, machine readable instructions for performance of the action associated with the selected one of the identified one or more images.

Abstract
A method that extracts features from frames of a video signal to perform an action includes receiving a query related to one or more frames of a video signal; extracting one or more features of the one or more frames; identifying one or more annotations associated with the one or more frames; identifying one or more images related to the one or more frames by comparing the extracted features with reference features from a first plurality of reference works, the first plurality of reference works organized using a clustering technique based on annotations; providing the identified one or more images along with action information associated with the identified one or more images, wherein the action information is related to an action to be performed; receiving a selection of one of the identified one or more images and providing machine readable instructions to perform the action.
