1. A method for organizing regions identified in image data, comprising:

  • averaging colors of regions of a spatial cluster to generate an average color;

    assigning the average color as a color of the spatial cluster;

    setting a size of the spatial cluster to a total number of pixels contained in the spatial cluster;

    forming one or more color clusters, each color cluster including regions of the image data having a color difference that is less than a color threshold;

    grouping two or more regions included in a color cluster into one of one or more spatial clusters if closest boundaries of the two or more regions are within a distance threshold;

    assigning each spatial cluster to a binary output plane;

    and eliminating regions from color or spatial clusters which are determined to be completely contained within other regions.
