A novel approach to video matting using automated scribbling by motion analysis

Video matting can be described as a method of extracting the foreground object from each frame of a video and composite (or transfer) it to a different background or a different video. An automatic scribbling approach based on the motion of the foreground object in a video is introduced. Probability maps (PMs) are computed by analysing the motion of object in the video. In the proposed technique the corrupted PMs are refined and reconstructed using morphological techniques. The frames are scribbled with reference to the reconstructed PMs. Closed form solution based matting technique uses the scribbled frame to yield the matte and the foreground.
