Title:
画像信号を処理する方法
Document Type and Number:
Japanese Patent JP6395655
Kind Code:
B2
Abstract:
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.
