2D and 3D image reconstruction for multi-channel EEG. a 2D image reconstruction on a multi-channel time series results in an image in 2D (multiple frames as multiple channels). b 3D image reconstruction on multi-channel time series results in 3D image volume, preserving temporal information of the input signal. The z-axis is the channel number, x is the size of the time window, y is the value of the signal
