Methods for using extracted features to perform an action associated with selected identified image
Methods and systems to perform methods comprising receiving, at a computer system from a first electronic device a first electronic media work; extracting one or more features therefrom; determining that at least a portion of the first electronic media work corresponds to a first reference media work based on a matching of the extracted features against a database of reference features; receiving, from a second electronic device, a query related to the first electronic media work; linking the query to action information in an action database based upon determining that at least a portion of the first electronic media work corresponds to the first reference media work; generating machine-readable instructions associated with the action to be performed based at least in part on the linking of the query to the action information; transmitting, to the second electronic device, the machine-readable instructions; and logging an event associated with the machine-readable instructions.
1. A method for associating an electronic work with an action, the electronic work comprising at least one of audio and video, the method comprising:
a) electronically extracting one or more features from a portion of the electronic work, wherein the features include a compact representation of the portion;
b) electronically identifying, at the computer system, a first reference work related to the portion by comparing the one or more features extracted from the portion with reference features from a first plurality of reference works using a near neighbor search of reference features that identifies one or more matches to the portion but does not guarantee to identify an exact match to the portion, wherein the reference features from the first plurality of reference works are organized using a clustering technique to eliminate a second plurality of reference works from being searched;
c) electronically determining an action information based on the identification of the electronic work, wherein the action information is related to an action to display an advertisement to be performed at a user electronic device; and
d) in response to a request to access the electronic work by the user electronic device, providing, to the user electronic device, machine readable instructions for performance of the action.
2. The method of claim 1 , wherein the portion of the electronic work comprises a portion of a video signal.
3. The method of claim 2 , wherein the one or more features extracted from the portion comprise a low-resolution copy of at least a portion of the portion of the video signal.
4. The method of claim 2 , wherein the one or more features extracted from the portion comprise average intensities of n times n blocks of pixels of at least a portion of the portion of the video signal.
5. The method of claim 2 , wherein the one or more features extracted from the portion comprise a pseudo-random sample of pixels from at least a portion of the portion of the video signal.
6. The method of claim 1 , wherein the action associated information is related to displaying an advertisement comprising video with the electronic work at the user electronic device.
7. The method of claim 1 , wherein the user electronic device is a personal computer.
8. The method of claim 1 , wherein the user electronic device is a cell phone.
9. The method of claim 1 , wherein the user electronic device is a set top box.
10. The method of claim 1 , wherein the portion of the electronic work comprises a portion of an audio signal.
11. The method of claim 10 , wherein the action information is related to presenting an advertisement comprising audio with the electronic work at the user electronic device.
12. The method of claim 1 , wherein the portion of the electronic work comprises a portion of a video signal and a portion of an audio signal.
13. The method of claim 12 , wherein the action information is related to presenting an advertisement comprising audio and video with the electronic work at the user electronic device.
