Multi-Layer Zero Crossing Rate

This code implements a more general version of the MLZCR as proposed in [1] for energy disaggregation.

This code can also be found in Matlab and Python code at (https://github.com/pascme05/MLZCR) the code implements a more general version of the MLZCR as proposed in [1] for energy disaggregation. In detail, arbitrary frames of signals are processed using multiple layers for possible zero crossings between a minimum and maximum value.

The code for the MLZCR is provided for Matlab and python implementation.

Inputs
x: frame of a signal with arbitrary length
nlayers: number of zero-crossing layers
xmin: static minimum value of the signal (optional)
xmax: static maximum value of the signal (optional)

Output
zc: number of zero crossings for each layer (dim: nlayers x 1)
zcr: zero crossing rate (dim: nlayers x 1)
