%GSP_DEMO_GRAPH_TV Reconstruction of missing sample on a graph using TV % % In this demo, we try to reconstruct missing sample of a piece-wise % smooth signal on a graph. To do so, we will minimize the well-known TV % norm defined on the graph. % % For this example, you need the unlocbox.

Modern signal processing often involves solving an optimization problem. Graph signal processing (GSP) consists roughly of working with linear operators defined by a graph (e.g., the graph Laplacian).

Description. Compute the TV norm of a signal on a graph
In this paper, we first provide an overview of core ideas in GSP and their connection to conventional digital signal processing, along with a brief historical perspective to highlight how concepts recently developed in GSP build on top of prior research in other areas.
