Fig. 11.From: Transient feature extraction method based on adaptive TQWT sparse optimization3d curve of adaptive parameter optimization. The figure shows the SAEWSE value in the two-dimensional grid search space of parameter (Q,r), the optimal parameter \((Q_{opt} = 6.2,\;r_{opt} = 8)\) is determined according to the minimum value of SAEWSE curveBack to article page
