| Abstract(in English) | Realtime video processing applications such as intruder detection system are now in demand and being developed. However, on a general purpose computers, it is difficult to guarantee that enough CPU resources can be surely be provided. A pseudo realtime video processing library RaVioli has been proposed for solving this problem. RaVioli conceals two types of resolutions, frame rate and the number of pixels, from programmers. This makes video and image processing programmings more intutive, but the performance may be lower by the abstraction overhead. To solve this problem, this paper proposes an improvement of RaVioli for supporting GPU and Cell/B.E. platforms which are very suitable for video processing. For using these platforms effectively, a deep knowledge about them has been required, and this would have been a burden to programmers. The proposition on this paper provides an easy-to-use framework for programmers. They can benefit from GPU or Cell/B.E. without rewriting their RaVioli programs and get high performance video processing. The result of experiment with some sample programs shows that the proposed method improves the performance 164-fold on CUDA and 5-fold on Cell/B.E. in maximum repectively. |
