class CONNECTIVITYLIB::ImagCoherence

Computes the imaginary part of complex coherency for every channel pair.

The estimator inherits the volume-conduction rejection property derived by Nolte et al. (NeuroImage, 2004): zero-lag mixing of independent sources contributes only to the real axis and is removed, so the returned edge weights reflect interactions with non-zero conduction delay only. The cross-spectral accumulation is delegated to Coherency::calculateImag; this class is the public entry point used by the dispatcher in Connectivity.

Imaginary-coherence estimator (Nolte et al. 2004); rejects zero-lag volume-conduction mixing.
