METHOD AND APPARATUS FOR ESTIMATING MOTION IN VIDEO, METHOD AND APPARATUS FOR STABILIZING VIDEO, AND COMPUTER-READABLE RECORDING MEDIUM |
| 摘要 |
A method of stabilizing a video is provided. The method includes detecting a feature point from a first frame; predicting a location of the feature point in a second frame based on a location of the feature point in the first frame and a predetermined parameter; detecting the feature point from the second frame; determining a distance between the predicted location and a location of the feature point detected from the second frame; and updating the parameter based on a location difference between the feature point detected in the first frame and the feature point detected in the second frame, in response to determining that the distance is within a predetermined threshold. |
