Notification systems and methods for notifying users based on face match
View Patent ↗A notification system notifies users when there is a match between images. The notification system includes a network interface receiving images from a plurality of user devices including a first user device and a second user device, a memory storing database and instructions, and a processor. The processor executes the instructions to function as an image processing unit processing the received images, a face recognition unit recognizing one or more faces in each received image, a face matching unit checking whether a face in a first image from the first user device matches a face in a second image from the second user device, a metadata processing unit processing metadata in each received image, and a notification unit notifying the first user device and the second user device in a case where the face in the first image matches the face in the second image.
1. A notification system that notifies users when there is a match between images, the notification system comprising:
a network interface configured to receive images from a plurality of user devices including a first user device and a second user device;
a memory storing database and instructions;
a processor executing the instructions to function as:
an image processing unit configured to process the received images;
a face recognition unit configured to recognize one or more faces in each received image;
a face matching unit configured to check whether a face in a first image from the first user device matches a face in a second image from the second user device;
a metadata processing unit configured to process metadata in each received image; and
a notification unit configured to notify the first user device and the second user device in a case where the face in the first image matches the face in the second image.
2. The notification system according to claim 1 , wherein the processor further executes the instructions to function as:
a relationship unit configured to relate a face with corresponding metadata.
3. The notification system according to claim 1 , wherein, in a case where a received image does not have metadata therein, the metadata processing unit is further configured to send a request for metadata to a corresponding user device and receive metadata from the corresponding user device.
4. The notification system according to claim 1 , wherein the face recognition unit is further configured to group same faces in the received images from each user device and set a representative face of the same faces.
5. The notification system according to claim 4 , wherein the face matching unit is further configured to calculate a difference between a first representative face in received images from the first user device and a second representative face in received images from the second user device.
6. The notification system according to claim 5 , wherein, in a case where the difference is between a first threshold and a second threshold, the face matching unit is further configured to calculate a similarity score between the metadata of the first representative face and the second representative face.
7. The notification system according to claim 6 , wherein, in a case where the similarity score is greater than or equal to a third threshold, the notification unit notifies the first and second user devices.
8. The notification system according to claim 1 , wherein the metadata includes personal information, geographical information, and image information.
9. The notification system according to claim 1 , wherein the database includes user information of each user.
10. The notification system according to claim 9 , wherein the first and second user devices are notified based on the user information.
11. A notification method for notifying users when there is a match between images, the notification method comprising:
receiving images from a plurality of user devices including a first user device and a second user device;
processing the received images;
recognizing one or more faces in each processed image;
checking whether a face in a first image from the first user device matches a face in a second image from the second user device;
processing metadata in each received image; and
notifying the first user device and the second user device in a case where the face in the first image matches the face in the second image.
12. The notification method according to claim 11 , further comprising:
relating a face with corresponding metadata.
13. The notification method according to claim 11 , further comprising:
in a case where a received image does not have metadata therein, sending a request for metadata to a corresponding user device and receiving metadata from the corresponding user device.
14. The notification method according to claim 11 , wherein face matching is checked by grouping same faces in the received images from each user device and setting a representative face of the same faces.
15. The notification method according to claim 14 , wherein the face matching is further checked by calculating a difference between a first representative face in received images from the first user device and a second representative face in received images from the second user device.
16. The notification method according to claim 15 , wherein, in a case where the difference is between a first threshold and a second threshold, the face matching is checked by calculating a similarity score between the metadata of the first representative face and the second representative face.
17. The notification method according to claim 16 , wherein, in a case where the similarity score is greater than or equal to a third threshold, the first and second user devices are notified.
18. The notification method according to claim 11 , further comprising:
storing database, which includes user information of each user.
19. The notification method according to claim 18 , wherein the first and second user devices are notified based on the user information.
20. A non-transitory computer readable storage medium including instructions that, when executed by a computer, cause the computer to perform a notification method for notifying users when there is a match between images, the notification method comprising:
receiving images from a plurality of user devices including a first user device and a second user device;
processing the received images;
recognizing one or more faces in each processed image;
checking whether a face in a first image from the first user device matches a face in a second image from the second user device;
processing metadata in each received image; and
notifying the first user device and the second user device in a case where the face in the first image matches the face in the second image.
