As digital video data becomes more pervasive, mining information from multimedia data becomes increasingly important. However, the huge computational requirement prohibits its wide use in practice. This paper presents some optimization techniques and parallel approaches to accelerate a real video mining application -goalmouth detection in soccer video. By tuning the application performance with efficient...
As digital video data becomes more pervasive, mining information from multimedia data becomes increasingly important. Although researches in multimedia mining area have shown great potential in daily life, the huge computational requirement prohibits its wide use in practice. Since our personal computer is shifting from uniprocessors to multicore processors, exploiting thread level parallelism in...
As multi/many core processors become prevalent, programming language is important in constructing efficient parallel applications. In this work, we build a multithreaded video mining application with Java, examine the thread profiling information and micro-architecture metrics to identify the factors limiting the scalability, and employ a number of ways to improve performance. Besides, we conduct...
