DUPLICATE IMAGE DETECTION FOR ELECTRONIC MEETINGS
A computer implemented method includes receiving an image of a meeting area from a first camera during an electronic conference call, detecting multiple faces in the image using a facial recognition model, receiving information from a secondary sensor to identify locations of participants in the meeting area, correlating the detected faces with the locations of participants, and generating a set of images of the participants that excludes detected faces that do not correspond to the locations of participants.
1 . A computer implemented method comprising:
receiving an image of a meeting area from a first camera during an electronic conference call;
detecting multiple faces in the image using a facial recognition model;
receiving information from a secondary sensor to identify locations of participants in the meeting area;
correlating the detected faces with the locations of participants; and
generating a set of images of the participants that excludes detected faces that do not correspond to the locations of participants.
2 . The method of claim 1 wherein the secondary sensor comprises a distance sensor and wherein the information corresponds to depth measurements the participants.
3 . The method of claim 2 wherein the depth measurements are of the faces of the participants.
4 . The method of claim 3 wherein detected faces having constant or linear depth are excluded from the set of images.
5 . The method of claim 2 wherein the distance sensor comprises a light detection and ranging (LIDAR) sensor.
6 . The method of claim 2 wherein the distance sensor comprises a time-of-flight (ToF) sensor.
7 . The method of claim 1 and further comprising transmitting the identified images to a remote participant device.
8 . The method of claim 1 wherein the secondary sensor comprises an infrared sensor and wherein the information corresponds to heat measurements of the participant.
9 . The method of claim 8 wherein heat measurements are of the faces of the participants.
10 . The method of claim 9 wherein detected faces having constant or linear heat measurements are excluded from the set of images.
11 . The method of claim 9 wherein detected faces having heat measurements not representative of a person are excluded from the set of images.
12 . A machine-readable storage device having instructions for execution by a processor of a machine to cause the processor to perform operations to perform a method, the operations comprising:
receiving an image of a meeting area from a first camera during an electronic conference call;
detecting multiple faces in the image using a facial recognition model;
receiving information from a secondary sensor to identify locations of participants in the meeting area;
correlating the detected faces with the locations of participants; and
generating a set of images of the participants that excludes detected faces that do not correspond to the locations of participants.
13 . The device of claim 12 wherein the secondary sensor comprises a distance sensor and wherein the information corresponds to depth measurements the participants.
14 . The device of claim 13 wherein the depth measurements are of the faces of the participants.
15 . The device of claim 14 wherein detected faces having constant or linear depth are excluded from the set of images.
16 . The device of claim 13 wherein the distance sensor comprises a light detection and ranging (LIDAR) sensor or a time-of-flight (ToF) sensor.
17 . The device of claim 12 wherein the operations further comprise transmitting the identified images to a remote participant device.
18 . The device of claim 12 wherein the secondary sensor comprises an infrared sensor and wherein the information corresponds to heat measurements of faces of the participant.
19 . A device comprising:
a processor; and
a memory device coupled to the processor and having a program stored thereon for execution by the processor to perform operations comprising:
receiving an image of a meeting area from a first camera during an electronic conference call;
detecting multiple faces in the image using a facial recognition model;
receiving information from a secondary sensor to identify locations of participants in the meeting area;
correlating the detected faces with the locations of participants; and
generating a set of images of the participants that excludes detected faces that do not correspond to the locations of participants.
20 . The device of claim 19 wherein the secondary sensor comprises a distance sensor, a light detection and ranging (LIDAR) sensor, or a time-of-flight (ToF) sensor and wherein the operations further comprise transmitting the identified images to a remote participant device.
