Spurious elements removal & Shape Recovery
-
Approach: Removing structure from the shock graph
implies a transform on the input data.
Spurious elements are indicated by "loops"
in the shock graph.
Removal of loops = Computation of higher degree
symmetries, performed by letting waves flow through.
NB: "Loops" can be bounded at infinity.
