Fig. 2From: Application of the normalized largest eigenvalue of structure tensor in the interpretation of potential field tensor dataDepth results estimated by the NDC of largest eigenvalue of structure tensor with different normalization functions, and the standard deviation in the Gaussian envelop is \(\delta x = \delta {\text{y } = \text{ }}0.01\). a By arithmetic mean; b by median; c by geometric mean; d 3D view of the normalized result by medianBack to article page
