Abstract: Provided is a video correction method comprising: extracting a common feature point from a number of video frames corresponding to a correction window size; extracting a trace of the feature point from the video frames; calculating an average value of the trace in the video frames; extracting a stabilized trace from a circular queue circular queue buffer using the trace and the average value; and applying a repositioning operation and a perspective warping operation to the video frames based on the stabilized trace to generate a stabilized video.
