Spatial temporal active contour interpolation for semi-automatic video object generation
Huan Luo, Alexandros Eleftheriadis · 1999
An active-contour interpolation approach is proposed for semi-automatic video object generation. In this approach, user can define the contour of the same video object on multiple frames and the computer interpolates the missing contours automatically. A typical active contour model is adapted and the contour interpolation problem is decomposed into two directional contour tracking problems and a merging problem. In addition, a new concept of parametric neighborhood template is introduced in order to improve the robustness of contour tracking.
