Abstract
An object movie is a set of images of a 3D object viewed from different angles, which allows the viewer to explore the object, turning, rotating and zooming in virtual space. In order to improve the display quality of the object movie, or even to integrate the object into a new background, the original background of the object movie should be removed. Although many techniques of video object segmentation have been proposed, no automatic method is suitable for removing the background of object movies. To obtain a better segmentation result, the user intervention is necessary. The purpose of this paper is to develop an interactive software tool for removing the background of object movies, which lets the users perform the work of background removal in less time with least intervention. As the first step, our software tool extracts an initial contour of each image in object movies efficiently. If the initial contours of some frames are not good enough, the users can manually correct some of those frames with some easy-to-use modification tools provided by our system. After user intervention, the verified segmentation results are used to refine other unverified frames with an automatic propagation process.
