| Abstract(in English) | As an object moves through the field of view of a camera, it undergoes changes in pose relative to the viewing camera, in illumination relative to light sources, and may even become partially occluded. This causes erroneous object-tracking results. To deal with this problem, we have proposed a method using a shape-constraint-based splitting snake. In this method, the approximate 3-D shape of the target object is assumed to be given, and the snake extracts the target using a reference contour which is sorted from the several contours prepared from the given shape. However, this method could obtain erroneous results in the case where the prepared contours do not include any appropriate ones. To solve this problem, this paper proposes a more efficient method, which introduces a new term to the objective function defined for the snake. This term is calculated from the variation amount of the pose of the approximate shape. By optimising the objective function, the proposed method can obtain the appropriate reference contour and track moving objects in the image sequence more accurately. |
