| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we propose a method for a fast multiple moving sound sources tracking based on PAST-IPLS method. In this method, a reduction of computational costs is achieved by reducing the number of microphones. In such a situation, when we extend the microphone width to prevent a degradation of resolution, it involves a lot of local minimum due to the spatial aliasing in the objective function. In this study, we set feasible regions every frequency bands to avoid the spatial aliasing. Moreover, a delayed sum array method is applied to reset the feasible regions. Several experimental results in actual environments show that the method can reduce the computational cost and improve the estimation accuracy. | |
