The Edge Feature Subtraction for Completing Video Matting

An automatic video matting method based on unsupervised matting using edge feature is proposed in this paper. Extract foreground and background objects from video sequences is an essential task as video matting. But it needs an automatic process to determine foreground and background area so the human effort can be reduced. We proposed a method to decide mechanical constraints using edge features on video matting. Edge features are used to find a gradient vector from each RGB color channel to obtain automatic scribbles. Comparing the results, alpha matte from our proposed method with ground truth has less than 0,01 in the MAE score.
