Camera motion estimation is very important for indexing and retrieving video information. In this paper, we propose a robust camera motion estimation and classification algorithm. Our camera motion estimation algorithm consists of optical flow estimation, iterative RANSAC (RANdom SAmple Consensus) multiple motion estimation, and long-term camera motion estimation through a shortest-path search. In this approach, we first estimate multiple global affine motions from the computed optical flow… Expand
