Abstract

A system and method for recognizing symbols and identifying users or services, including the displaying of an image or video clip on a display device in which identification information is embedded in the image or video clip, the capturing the image or video clip on an imaging device, the transmitting of the image or video clip from the imaging device to a communication network, the transmitting of the image or video clip from the communication network to a processing and authentication server, the processing of the information embedded in the image or video clip by the server to identify logos, alphanumeric characters, or special symbols in the image or video clip, and converting the identified logos or characters or symbols into a digital format to identify the user or location of the user or service provided to the user, and the using of the processed information in digital format to provide one or more of a variety of additional applications.

Claims

1. A method for recognizing symbols and identifying users or services, the method comprising:

displaying an image or video clip on a display device in which identification information is embedded in the image or video clip;

capturing the image or video clip on an imaging device;

transmitting the image or video clip from the imaging device to a communication network;

transmitting the image or video clip from the communication network to a processing and authentication server;

processing the information embedded in the image or video clip by the server to identify logos, alphanumeric characters, or special symbols in the image or video clip, and converting the identified logos or characters or symbols into a digital format to identify the user or location of the user or service provided to the user;

2. The method of claim 1, wherein,

the processed information in digital format is used to provide one or more additional services to the user.

3. The method of claim 1, wherein:

the embedded information is a logo;

4. The method of claim 1, wherein:

the nature or character of the image or video clip serves as all or part of the identifying information.

5. The method of claim 1, wherein:

the embedded information is signal that is spatially or temporally modulated on the screen of the display device.

6. The method of claim 1, wherein

the embedded information is alphanumeric characters;

7. The method of claim 1, wherein:

the embedded information is a bar code.

8. The method of claim 1, wherein:

the embedded information is a sequence of signals which are not human readable but which are machine readable.

9. The method of claim 1, wherein:

the communication network is a wireless network.

10. The method of claim 1, wherein:

the communication network is a wireline network.

11. The method of claim 1, wherein:

the display device further displays additional information which identifies the type and location of the display device.

12. A system for recognizing symbols and identifying users or services, the system comprising:

a remote server that prepares and transmits an image or video clip to a local node;

a local node that receives the transmission from said server;

a display that presents the image or video clip on either physical or electronic medium;

an imaging device for capturing the image or video clip in electronic format;

a communication module for converting the captured image or video clip into digital format and transmitting said digital image or video clip to a communication network;

a communication network that receives the image or video clip transmitted by the communication module, and that transmits such image or video clip to a processing and authentication server; and

a processing and authentication server that receives the transmission from the communication network, and completes the processing to identify the location of the display, the time the display was captured, and the identify of the imaging device.

13. The system of claim 12, wherein:

remote server is one or a plurality of servers or computers.

14. The system of claim 12, wherein:

the local node is a node selected from the group consisting of a television set, a personal computer running a web browser, an LED display, or an electronic bulletin board.

15. The system of claim 12, wherein:

the display and the imaging device are combined in one unit of hardware.

16. The system of claim 12, wherein:

there is a communication link between the processing and authentication server and the remote server which allows the execution of additional servers to the user.

17. A method recognizing symbols and identifying users or services, the method comprising:

resizing a target image or video clip in order to compared the resized image or a video clip to a pre-existing database of images or video clips;

determining the best image scale by first searching among all scales where the score is above a pre-defined threshold and then choosing the best image scale among the various image scales tested;

repeating all prior procedures for multiple parts of the object image or video clip, to determine the potential locations of different templates representing various parts of the object;

iterating the combinations of all permutations of the templates for the respective parts of the object in order to determine the permutation with the best match with the object;

determining if the best match permutation is sufficiently good to conclude that the object has been correctly identified.

18. The method of claim 17, wherein:

the best image scale is not determined by applying pre-defined thresholds, but rather by one or more of the techniques of applying other score functions, or weighting the image scales of several scale sets yielding the highest scores, or using a parametric fit to the whole range of scale sets based on their relative scores.

19. The method of claim 17, wherein:

the scale ranges for the various parts of the object during template repetition may be varied for each part in order to determine the optimal image scale for each part.

20. A computer program product, comprising a computer data signal in a carrier wave having computer readable code embodied therein for causing a computer to perform a method comprising:

displaying an image or video clip on a display device in which identification information is embedded in the image or video clip;

capturing the image or video clip on an imaging device;

transmitting the image or video clip from the imaging device to a communication network;

transmitting the image or video clip from the communication network to a processing and authentication server;

processing the information embedded in the image or video clip by the server to identify logos, alphanumeric characters, or special symbols in the image or video clip, and converting the identified logos or characters or symbols into a digital format to identify the user or location of the user or service provided to the user;

using the processed information in digital format to provide one or more of a variety of additional applications.
