ChannelBinDiffT< T > Class Template Reference

We first bin the channels then we calculate the difference between pairs of channels in a datastream. E.g. For binning, if we bin 4 samples in each channel we will have 4 times less samples per channel E.g. For subtracting if we have 4 channels we end up with 2 channels. The channels will be channel_1 - channel_2 channel_3 - channel_4 This is the same as combining binning and subtracting channels. This will not work if you provide single channel data! More...
