Total Variation (TV) and Asymmetric Total Variation (ATV) in CWI is edge-preserving optimisation regularisation within the XWITM toolbox. This provides the capability to steer early iterations away from local minima, to recover sharp, accurate and well-defined salt boundaries, and to generate implicit salt and sediment flooding without manual intervention and explicit identification of salt-related reflectivity.
