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.

Method and apparatus for estimating motion in video, method and apparatus for stabilizing video, and computer-readable recording medium

An apparatus, a method, and a recording medium for image stabilization are provided. The image stabilization method includes receiving an image that is captured by a camera, detecting a motion of the image, predicting a motion of the image, using a Kalman filter, comparing the detected motion with the predicted motion, and updating a parameter of the Kalman filter based on a result of the comparing.

Apparatus, method and recording medium for image stabilization

A method of shortening a video includes: determining shortened key frames by selecting one key frame for every preset time interval of a time line of the video or for every preset position interval of a camera which captures the video, from among original key frames of the video; determining event key frames from which an event is detected, from among the original key frames; determining event-preserved key frames using the shortened key frames and the event key frames; and generating a shortened video using the event-preserved key frames.
