Abstract

Disclosed is a method of removing an obstacle from a video stream by collaboratively gathering video streams from multiple parties using a peer-to-peer (P2P) network. The system determines the best or most appropriate video stream to fill the video to remove the obstacle from the P2P shared video streams.

System and Method for Obstruction Removal in Video Stream

While capturing video sometimes a person or object can be in front of the camera and create an obstacle. The following diagram (Figure 1) shows an example of a person being in the frame of video. In this example, video is being captured but by chance a person appeared in front of camera and the obstacle is created.

Figure 1: Obstacle scenario: Four users are capturing individual videos of an event

Figure 2: Obstacle scenario: While capturing video, User A moves to location X, and User D moves to location Y. These movements create obstacles for A, B, and C, or another user that takes B's position. An obstacle can also be created by any other object that intercepts the view of the camera.

At present, there is not a mechanism available to remove the obstacle in video in a collaborative way.

The novel contribution is a method and system to remove an obstacle from a video stream by collaboratively gathering video streams from multiple parties using a peer-to-peer (P2P) network. When multiple individuals capture video of any event or area, then collocated volunteer users (who are capturing video) can create a temporary collaboration using a P2P network. While capturing any video, if any obstacle appears

in one or more video camera view, then the said video camera receives the video stream from another video camera stream in the defined temporary P2P network. Gathering of video stream from temporary P2P network is a dynamic approach. If an obstacle is detected by any camera, then the best or most appropriate video stream is gathered from the temporary P2P network to fill the obstacle.

The system uses sensor or Global Positioning System (GPS) coordinates to identify peer video cameras taking video of the same event and time. The system makes known to other individuals filming the event, who volunteer the information, the opportunity to join the P2P network and share video in order to remove obstructed views within the video stream. The system processes the voluntee...
