Using synchronous recording by front and back smartphone cameras for creating immersive video content and for video conferencing

1. A method of creating a video presentation, comprising:

obtaining a first front-camera video stream and a first back-camera video stream that are recorded synchronously using a first device having a front-camera and a back-camera;

extracting a first image of a first presenter from the first front-camera video stream by removing background objects from the first front-camera video stream;

obtaining a second front-camera video stream and a second back-camera video stream that are recorded synchronously using a second device having a front-camera and a back-camera;

extracting a second image of a second presenter from the second front-camera video stream by removing background objects from the second front-camera video stream;

determining that the first back-camera video stream and the second back-camera video stream are complimentary views;

constructing a panoramic view by combining the first back-camera video stream and the second back-camera video stream; and

superimposing the first image of the first presenter and the second image of the second presenter onto to the panoramic view to provide the video presentation.

2. The method, according to claim 1 , further comprising:

providing the video presentation to the first device of the first presenter and to the second device of the second presenter to allow the presenters to view the video presentation and to interact.

3. The method, according to claim 1 , wherein each of the images are at least one of: semi-transparent, an outline, a silhouette, or a stylized/enhanced graphical version of a corresponding one of the presenters.

4. The method, according to claim 1 , wherein the first presenter controls size and position of the image of the first presenter superimposed onto the panoramic view and the second presenter controls size and position of the image of the second presenter superimposed onto the panoramic view.

5. The method, according to claim 4 , wherein the presenters control the size and position of the images of the presenters using at least one of: a remote control with one-handed manipulation, eye-tracking, sensors that track 3D trajectory and gesture recognition made with a free hand of the presenter with a wearable device, or a camera-based 3D gesture recognition mechanism.

6. The method, according to claim 1 , wherein the devices are smartphones.

7. The method, according to claim 1 , wherein the devices use at least one of: GPS technology or IMU (Inertial Measurement Unit) technology.

8. The method, according to claim 7 , wherein the at least one of GPS technology or IMU technology is used in connection with determining that the first back-camera video stream and the second back-camera video stream are complimentary views.

9. The method, according to claim 7 , wherein the at least one of GPS technology or IMU technology is used in connection with constructing the panoramic view.

10. A non-transitory computer readable medium containing software that creates a video presentation from a first front-camera video stream and a first back-camera video stream that are recorded synchronously using a first device having a front-camera and a back-camera and a second front-camera video stream and a second back-camera video stream that are recorded synchronously using a second device having a front-camera and a back-camera, the software comprising:

executable code that extracts a first image of a first presenter from the first front-camera video stream by removing background objects from the first front-camera video stream;

executable code that extracts a second image of a second presenter from the second front-camera video stream by removing background objects from the second front-camera video stream;

executable code that determines that the first back-camera video stream and the second back-camera video stream are complimentary views;

executable code that constructs a panoramic view by combining the first back-camera video stream and the second back-camera video stream; and

executable code that superimposes the first image of the first presenter and the second image of the second presenter onto to the panoramic view to provide the video presentation.

11. The non-transitory computer readable medium, according to claim 10 , further comprising:

executable code that provides the video presentation to the first device of the first presenter and to the second device of the second presenter to allow the presenters to view the video presentation and to interact.

12. The non-transitory computer readable medium, according to claim 10 , wherein each of the images are at least one of: semi-transparent, an outline, a silhouette, or a stylized/enhanced graphical version of a corresponding one of the presenters.

13. The non-transitory computer readable medium, according to claim 10 , wherein the first presenter controls size and position of the image of the first presenter superimposed onto the panoramic view and the second presenter controls size and position of the image of the second presenter superimposed onto the panoramic view.

14. The non-transitory computer readable medium, according to claim 13 , wherein the presenters control the size and position of the images of the presenters using at least one of: a remote control with one-handed manipulation, eye-tracking, sensors that track 3D trajectory and gesture recognition made with a free hand of the presenter with a wearable device, or a camera-based 3D gesture recognition mechanism.

15. The non-transitory computer readable medium, according to claim 10 , wherein the devices are smartphones.

16. The non-transitory computer readable medium, according to claim 10 , wherein the devices use at least one of: GPS technology or IMU (Inertial Measurement Unit) technology.

17. The non-transitory computer readable medium, according to claim 16 , wherein the at least one of GPS technology or IMU technology is used in connection with determining that the first back-camera video stream and the second back-camera video stream are complimentary views.

18. The non-transitory computer readable medium, according to claim 16 , wherein the at least one of GPS technology or IMU technology is used in connection with constructing the panoramic view.
