- 論文の詳細を見る
This paper proposes an efficient means for tracking a deformable object by integrating active contour models and mean shift algorithm. The active contour models that can describe complex object boundary and track the dynamic object are widely used for tracking and extracting these objects. However, the results of object tracking based on the active contour models are very sensitive to the location of the initial curve. Therefore, we should move the initial curve in advance to the position close to the object. Our proposed system performs in two stages: object localization and object extraction. Experiments for tracking a moving object in actual image sequences confirmed the effectiveness of the proposed system. The results demonstrate the validity of our approach.
