Abstract

The advanced techniques for video processing and computer graphics enables a sign language education system to appear. The system is capable of showing a sign language motion for an arbitrary sentence using the captured video clips of sign language words. In this paper, a method is suggested which generates the frames between the last frame of a word and the first frame of its following word in order to animate hand motion. In our method, we find hand locations and angles which are required for inbetween frame generation, capture and store the hand images at those locations and angles. The inbetween frames generation is simply a task of finding a sequence of hand angles and locations. Our method is computationally simple and requires a relatively small amount of disk space. However, our experiments show that inbetween frames for the presentation at about 15 fps(frame per second) are achieved so that the smooth animation of hand motion is possible. Our method improves on previous works in which computation cost is relatively high or unnecessary images are generated.
