1. A method comprising:

  • obtaining at least one frame of pixel data;

    processing the at least one frame of pixel data to generate a hair-identification probability map at least in part by;

    identifying a plurality of pixel columns that cross an identified head contour; and

    for each pixel column in the plurality of pixel columns;

    performing a color-based segmentation of the pixels in the pixel column into a foreground segment, a hair segment, and a background segment; and

    assigning the pixels in the hair segment an increased foreground-probability value in the hair-identification probability map; and

    generating a persona image by extracting pixels from the at least one frame of pixel data based at least in part on the generated hair-identification probability map.
