| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We propose a design method of vertex domain sampling for graph signals that guarantees perfect reconstruction. The existing method based on generalized graph sampling theory assumes only the sparsity of sampling matrices. We consider obtaining the sampling matrix as vertex domain sampling using filters with the locality. In this setting, obtained samples are combinations of signal values within a limited number of hops. It means that sampling in large graphs can be partitioned into localized problems. We formulate an optimization problem for designing selection matrices under the assumption that the graph filter is given. In the experiments, our method presents localized samples without compromising performance. | |
