eelbrain.edge_detector

eelbrain.edge_detector(signal, c=0, offset=False, name=None)

Neural model for auditory edge-detection, as described by [1] and used in [2]

Parameters:

• signal (NDVar) – Signal on which to detect edges (e.g. a gammatone filterbank).

• c (float) – Saturation parameter (see [1]).

• offset (bool) – Detect offsets (instead of onsets).

• name (str) – Name for the returned NDVar.
