A method for constructing wavelet transforms of functions defined on the vertices of an arbitrary finite weighted graph.

Example: spectral graph wavelets on Minnesota road graph

wavelets on graph (minesota)

(a) vertex at which wavelets are centered; (b) scaling function; (c)-(f) wavelets, scales 1-4.
