METHOD AND APPARATUS FOR ESTIMATING IMAGE OPTICAL FLOW |
| 摘要 |
An apparatus and method of estimating an image optical flow are provided. The method includes receiving temporally-consecutive first and second images; calculating rates of change of brightness values of pixels in the received temporally-consecutive first and second images; calculating a first optical flow estimation result value of a first pixel within the first image and a second optical flow estimation result value of a second pixel within the second image by using the calculated rates of change; comparing the first optical flow estimation result value with the second optical flow estimation result value; and correcting the first optical flow estimation result value and the second optical flow estimation result value by using a result of the comparison. |

1. A method of estimating image optical flow, the method comprising:
receiving a first image and a second image, the first image and the second image being temporally consecutive with each other; calculating rates of change of brightness values of pixels in the first image and the second image; calculating a first optical flow estimation result value of a first pixel within the first image and a second optical flow estimation result value of a second pixel within the second image by using the calculated rates of change; comparing the first optical flow estimation result value with the second optical flow estimation result value; and correcting the first optical flow estimation result value of the first image and the optical flow estimation result value of the second image by using a result of the comparison. |
