Abstract

The invention provides a internet hosted system to find, compare, contrast and identify similar characteristics among two or more individuals or objects using a digital camera, cellular telephone camera, wireless device for the purpose of returning information regarding similar objects or faces to the user The system features classification of images from a variety of Internet accessible sources, including mobile phones, wireless camera-enabled devices, images obtained from digital cameras or scanners that are uploaded from PCs, third-party applications and databases. Once classified, the matching person'"'"'s name, or the matching object, image and associated meta-data is sent back to the user. The image may be manipulated to emphasize similar characteristics between the received facial image and the matching facial image. The meta-data sent down with the image may include sponsored links and advertisements.

Claims

1. A method for matching an unknown image of an individual with a known image of another individual, the method comprising:

acquiring an unknown facial image of an individual;

transmitting the unknown facial image from a sender'"'"'s computer over the Internet to an image classification server;

analyzing the facial image at the image classification server to determine if the unknown facial image is acceptable;

processing the unknown facial image to create a processed image;

comparing the processed image to a plurality of database processed images;

matching the processed image to a database processed image of the plurality of database processed images to create matched images, wherein the database processed image is a facial image of another individual;

determining a perception value of the matched images; and

transmitting the matched images and the perception value to the sender over the Internet.

2. The method according to claim 1 wherein the processed image is processed as a primary feature vector and the plurality of database processed images is a plurality of database feature vectors, and wherein comparing the processed image to a plurality of database processed images comprises comparing the primary feature vector to each of the plurality of database feature vectors.

3. The method according to claim 2 wherein matching the processed image to a database processed image of the plurality of database processed images to create matched images comprises selecting a database feature vector with a value that is most similar to the value of the primary feature vector.

4. The method according to claim 1 wherein the plurality of database processed images comprises at least 10,000 database processed images.

5. The method according to claim 2 wherein comparing the processed image to a plurality of database processed images further comprises applying a statistical model based on human perception as determined by user'"'"'s votes of previous third party matched images.

6. The method according to claim 1 wherein the plurality of database processed images comprises from 50,000 database processed images to 100,000 database processed images.

7. The method according to claim 1 wherein the method occurs within a time period of 60 seconds.

8. The method according to claim 1 further comprising filtering the database processed image to provide a preferred database processed image for the matched images.

9. The method according to claim 2 wherein the primary feature vector and each of the plurality of database feature vectors are based on a plurality of factors comprising facial expression, hair style, hair color, facial pose, eye color, texture of the face, color of the face and facial hair.

10. The method according to claim 1 wherein the unknown facial image is transmitted as an electronic mail attachment.

11. The method according to claim 1 wherein the unknown facial image is transmitted as an HTTP upload.

12. The method according to claim 1 wherein the unknown facial image is a JPEG image.

13. The method according to claim 1 wherein image classification server comprises an input module, a transmission engine, facial recognition software, an input feed, a feature vector database, a perception engine and an output module.

14. The method according to claim 1 wherein the matched images and perception value are transmitted to a sender'"'"'s web page on a web site.

15. The method according to claim 1 wherein the perception value ranges from 0% to 100%.

16. The method according to claim 1 wherein analyzing the unknown facial image at the image classification server comprises determining if a plurality of facial image factors are acceptable, the plurality of facial image factors comprising the lack of a facial image, the lack of eyes, uneven lighting, the brightness of the facial image, pose angle of the facial image, relative size of the facial image and pixel strength of the facial image.

17. The method according to claim 1 further comprising transmitting a biography summary of a celebrity of the matched image from the image classification server to the sender.

18. A method for matching an unknown image of an individual with a known image of another individual, the method comprising:

acquiring an unknown digital facial image of an individual;

wirelessly transmitting the digital facial image from a mobile communication device over a wireless network to an image classification server;

processing the digital facial image at the image classification server to create a primary feature vector for the digital facial image;

comparing the primary feature vector to a plurality of database feature vectors, each of the plurality of database feature vectors corresponding to a database processed image;

selecting a database feature vector that best matches the primary feature vector to create matched images; and

transmitting the matched images to the mobile communication device.

19. A system for matching an unknown facial image of an individual with an image of a celebrity, the system comprising:

a computer comprising means for acquiring a digital facial image of an individual and means for transmitting the digital facial image over a network;

an image classification server for receiving the digital facial image from the computer, the image classification server comprising

means for analyzing the digital facial image,

means for processing the digital facial image to generate a processed image,

means for comparing the processed image to a plurality of database processed images,

means for matching the processed image to a database processed image of the plurality of database processed images to create matched images,

means for determining a perception value of the matched images, and

means for transmitting the matched images and the perception value to the computer over a network; and

a network for transmissions between the computer and the image classification server.

20. The system according to claim 19 wherein the image classification server further comprises means for applying a statistical model based on human perception as determined by user'"'"'s votes of previous third party matched images.
