The bandpower function calculates the average power of a signal within a specified frequency range.
Refer to the following documentation to learn more about the bandpower function:
Ensure that your data is preprocessed correctly. This includes converting your wavelength data into a form that can be interpreted as a frequency range and using the diffuse reflectance as the amplitude of the signal to apply the function on the spectrum.
The Kaiser-Teager energy operator is used to estimate the instantaneous energy of a signal. For spectral data, you can apply it to the reflectance values to assess the "energy" or "intensity" variation across wavelengths.
Note: The interpretation of results from these methods in the context of your spectral data might differ from typical time-series applications. Consider the physical meaning of "power" and "energy" in your specific application.
