Graph Signal Processing for Heterogeneous Change Detection Part I: Vertex Domain Filtering. (arXiv:2208.01881v1 [cs.CV])

This paper provides a new strategy for the Heterogeneous Change Detection
(HCD) problem: solving HCD from the perspective of Graph Signal Processing
(GSP). We construct a graph for each image to capture the structure
information, and treat each image as the graph signal. In this way, we convert
the HCD into a GSP problem: a comparison of the responses of the two signals on
different systems defined on the two graphs, which attempts to find structural
differences (Part I) and …
