Video segmentation apparatus and control method thereof

The present invention relates to a video segmentation device and method. In particular, the video segmentation device and method are capable of extracting a desired object by using an adaptive local window in the video. The method for controlling a video segmentation device according to the present invention comprises the processes of inputting a video in a frame unit; estimating a movement of an object to be separated from the inputted video to determine locations of windows corresponding to the object; adjusting at least one among the sizes and intervals of the windows existing in the determined locations of the windows by using at least one video characteristic; and separating the object from the imputed video by using the windows in which at least either the sizes or the intervals are adjusted.
