1. A method of encoding a fringe pattern image, said method comprising the steps of:

  • demodulating said image to provide a phase map structure of said image;

    identifying and removing any singularities in said phase map structure to create a continuous phase map structure, wherein each of said singularities is removed by adding to said phase map structure a phase spiral of equal charge magnitude and opposite charge sign to said singularity being removed;

    removing 2π

    phase discontinuities from said continuous phase map; and

    separately encoding said singularities and said continuous phase map structure as an encoded representation of said image.
