| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The problem of detecting the occurrence of target events in a given data sequence can be found in many fields , such as signal processing, pattern recognition, and image processing. We propose an event prediction method by using the Bayesian hidden Markov Model (HMM) and apply it to a video dataset of an actual soccer game. In this method, time-series data on the players' position are estimated from the video dataset and modeled with the HMM. The accuracy of this event prediction method can be improved by modifying the duration-modeling capability of the HMM, since a geometric distribution is used as its duration probability. In this paper, we use a generalized HMM in the event prediction algorithm for improving the duration-modeling capability. In addition, we test the efficiency of the proposed method with a video dataset of J-league soccer matches. | |
