1. A method of performing blood constituent analysis, comprising:

  • receiving a series of captured images that contain a digital signature of absorbed, transmitted and scattered light from a soft tissue appendage;

    determining a power spectral density (PSD) time series data from the digital signature;

    performing one of a model-based analysis to transform the PSD time series data to a noiseless model or a signal density-based analysis to segregate a signal associated with the PSD time series data into subspaces which are quantified;

    using a genetic algorithm to estimate a level of blood constituent from the noiseless model or the quantified subspaces; and

    communicating the level of blood constituent in a format suitable for display.
