In this paper, we propose a method for tracking a video object in an ordered sequence of two-dimensional images, where the outcome is the trajectory of the video object throughout the time sequence of images. This method is designed to run in real-time in a synchronous video collaboration environment, and is used for producing dynamic object annotations for enhanced video content understanding. A dynamic object is one whose location or size in the video frame constantly changes, due to the camera motion, its own motion, or both. We suggest a novel method for finding the trajectory of the object in the intermediate frames given the locations and shapes of the object in two end frames. In addition to the shape and location information of the object, its texture information in the end frames is used to predict the location and its search space in the intermediate frames.
