The bottom level shows the frequency representation of a signal, which decomposes both the approximation and details coefficients.
LH (low high) is generated by the approximation coefficients (low-pass filter) in X direction and details coefficients (high-pass filter) in Y direction (see Fig. 1).
Moreover, only Hotelling for SD and CV are computed based on details coefficients because those coefficients are the most reliable and appropriate for monitoring variance.
