Slowing and Loss of Complexity in Alzheimer's EEG: Two Sides of the Same Coin?
Figure 1
Wavelet transform realization via lifting scheme (a) Forward transformation. (b) Inverse transformation. The boxes labeled by stand for delays (over one sample). The boxes and represent downsampling and upsampling by a factor of two, respectively; in the latter a zero is inserted after every sample, whereas in the former, every second sample is removed. The lifting scheme repeats two primitive steps: prediction and update .
