The output is compared to a hard threshold, selected according to P FA (Figure1).

Because of errors in the database, a hard threshold cannot be used for land and sea.

Furthermore, intracellular recordings suggest that a hard threshold is a rough approximation and an exponential voltage-dependent spiking intensity is more realistic [33].

The SL0, IAA, and SLIM algorithms are initialized based on an l 2-norm solution with incorporating a hard threshold set to − 20 dB.

The SALSA is improved by adding a hard threshold de-noising to obtain optimal sparse coefficients of steady modulation and impact modulation components.

In order to keep the most meaningful block information and just reduce the noise, we should use a zigzag thresholding, instead of a hard thresholding.

Thus, we want to avoid the decision based on a hard thresholding and propose an approach that exploits a modeling of the power ratios as was similarly proposed by the authors in[31].

The denoising procedure for the 3D tensor ( {mathcal{Z}}_x ) consists of a hard thresholding of the coefficients of the transformed tensor ( mathcal{T}left({mathcal{Z}}_xright) ), followed by the inverse transformation.
