The movement of all points was automatically tracked using a two-dimensional cross-correlation tracking algorithm [37].
The first arrivals at time 50 s are aligned using a waveform cross-correlation.
Raw particles were windowed using a local cross-correlation function based method (Rath and Frank, 2004).
Phase encoded maps were computed using a linear cross-correlation analysis and projected on the corresponding flattened cortical surface.
The time-varying noise effect can be reduced by using an estimate of speech cross-correlation, that is, (8).
Finally, we use a windowed waveform cross-correlation based uncertainty estimation method for potential quality control purposes.
We examined such expected feature further by using a cross-correlation analysis.
We estimated the location of the source using a cross-correlation analysis of waveform envelopes.
The stacks were first aligned using a cross-correlation procedure and then converted into optical densities.
This was confirmed using a cross-correlation analysis.
