Abstract

A computer implemented method for processing video is provided. A first image and a second image are captured by a camera. A feature present in the first camera image and the second camera image is identified. A first location value of the feature within the first camera image is identified. A second location value of the feature within the second camera image is identified. An intermediate location value of the feature based at least in part on the first location value and the second location value is determined. The intermediate location value and the second location value are communicated to a physics simulation.

Claims

1. A computer implemented method for processing video comprising:

capturing a first image and a second image from a camera;

identifying a feature present in the first camera image and the second camera image;

determining a first location value of the feature within the first camera image;

determining a second location value of the feature within the second camera image;

estimating an intermediate location value of the feature based at least in part on the first location value and the second location value; and

communicating the intermediate location value and the second location value to a physics simulation.

2. A computer implemented method for processing video comprising:

capturing a current image from a camera wherein the current camera image comprises a current view of a participant;

retrieving, from a memory, a previous image comprising a previous view of the participant;

determining a first location value of the participant within the previous image;

determining a second location value of the participant in the current camera image and in the previous image;

estimating an intermediate location value of the participant based at least in part on the first location value and the second location value; and

communicating the intermediate location value and the second location value to a physics simulation.

3. The computer implemented method of claim 2, further comprising:

after communicating the intermediate location value and the second location value to a physics simulation, designating the current image as the previous image.

4. The computer implemented method of claim 2, further comprising displaying a representation of a virtual object on the video monitor wherein the participant can view a current trajectory of the virtual object as displayed on the video monitor.

5. The computer implemented method of claim 4, further comprising identifying a virtual collision between the participant and the virtual object based at least in part on the intermediate location value communicated to the physics simulation.

6. The computer implemented method of claim 5, further comprising displaying the virtual object traveling along a post-collision trajectory different than the previously displayed current trajectory.

7. The computer implemented method of claim 2 further comprising:

determining a movement vector of the participant based at least in part on the first location value and the second location value; and

communicating the movement vector of the participant to a physics simulation.

8. The computer implemented method of claim 7 wherein the movement vector is three-dimensional.

9. A computer system for processing video comprising:

a camera configured to capture a current image;

a memory configured to store a previous image and the current image;

a means for determining a first location value of the participant within the previous image;

a means for determining a second location value of the participant in the current camera image and in the previous image;

a means for estimating an intermediate location value of the participant based at least in part on the first location value and the second location value; and

a means for communicating the intermediate location value and the second location value to a physics simulation.

10. A tangible computer readable medium comprising software that, when executed on a computer, is configured to:

capture a current image from a camera wherein the current camera image comprises a current view of a participant;

retrieve, from a memory, a previous image comprising a previous view of the participant;

determine a first location value of the participant within the previous image;

determine a second location value of the participant in the current camera image and in the previous image;

estimate an intermediate location value of the participant based at least in part on the first location value and the second location value; and

communicate the intermediate location value and the second location value to a physics simulation.
