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; 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.

Abstract
Disclosed herein are systems and methods for persona identification using combined probability maps. An embodiment takes the form of a method that includes obtaining at least one frame of pixel data; processing the at least one frame of pixel data to generate a 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.

16. An apparatus comprising:
-
a hair-identification module that is configured to generate a hair-identification probability map based on at least one frame of pixel data 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 a persona extraction module configured to generate a persona image by extracting pixels from at least one frame of pixel data based at least in part on the generated hair-identification probability map. - View Dependent Claims (17, 18, 19, 20)
