Optical Flow for Large Motion Using Gradient Technique

Abstract

In this paper, we present the gradient-based optical flow method that estimates the two-dimensional velocity of object motion. a multi-resolution smoothing operation proposes in this paper as a pre-processing step for overcoming the difficulty of large motion estimation by gradient-based optical flow techniques. the effectiveness of the proposed method has confirmed by applying image sequence of large motion experimental results with an image sequence show a qualitative improvement.
