本報告では,輸送問題の解法に基づく移動領域の抽出手法を提案する.
動画像フレーム間の領域の対応関係を輸送問題と見なし,この問題を解くことで移動領域を抽出する.
領域の対応関係に基づくため,複雑な背景下での移動領域の抽出や追跡などが可能である.
実験を通して提案手法の有効性を示す. |

In this report , we propose a moving object detection method based on a solution the transportation problem.
We regard the regions in the current frame as sources, the regions in the target frame as destinations, and the total distances among regions as the transportation cost.
The solution of the transportation problem minimizing the total cost gives the correspondences of regions in the different frames.
The correspondences are represented by flows.
Each flow carries information about the pair of corresponding regions, the distance between the regions, and the amount of the transported pixels.
The proposed method can detect and track the moving regions by using the flows.
We demonstrate the effectiveness by means of various experiments. |
