The program allows users to draw around the tree outline in the first frame of the video, and then make a model of the tree and track the movement of branches and leaves in the video. Algorithms copy this movement, enabling the software to generate trees that are slightly different from each other. Li says the program would be a helpful tool for animators and computer game designers. “Our system will make it faster and cheaper for animators to create animated backgrounds,” he says. “In the future, we want to use this same technique to animate other objects like clouds, water, fire, and smoke.”

Similar technologies are already available in Europe and Asia, but Hsu says those technologies are very sensitive and unreliable. “The technology has been there for a couple of years, but not here,” Hsu says. “There are clearly some problems with it that prevent its deployment in North America. We are trying to optimize the broadcast networks to a stage where Canadian TV companies will consider them.” Hsu’s research has resulted in improved mobile TV broadcast performance and cell phones that broadcast more channels at once while reducing their channel-switching delay. Hsu also has improved the overall broadcast quality and extended battery life, which are features that are missing in mobile broadcast TV systems overseas. Hsu is currently working to establish mobile TV broadcasts through Wi-Fi and other wireless networks.
