Method for Graph Based Processing of Signals |
| 摘要 |
A method processes a signal by first constructing a graph from the signal, and then determining a graph matrix from the graph and the signal. A Krylov-based subspace is determined based on the graph matrix and the signal. A filter for the Krylov subspace is determined. The filter transforms the signal to produce a filtered signal, which is output. |

1. A method for processing a signal, comprising the ordered steps of:
constructing a graph from the signal; determining a graph matrix from the graph and the signal; determining a Krylov-based subspace based on the graph matrix and the signal; determining a filter for the Krylov-based subspace, wherein the filter transforms the signal to produce a filtered signal; outputting the filtered signal, wherein the steps are performed in a processor. |
