Examples of the M-function that maps the magnitude of the structure tensor. If the magnitude of the structure tensor is too low, the magnitude is set to zero for the control tensor, such that no highpass information is used in this part of the data. The overshoot is intended to amplify structures that have a magnitude that is slightly above the noise threshold.
