Generation of Hair Model from 2D Image

Abstract

This paper proposes a method to generate realistic hair model for individuals based on image processing, . The analysis and recognition of hair strands by image processing provide valuable data, particularly hair outline and the flow direction of the hair for the modeling of realistic hair model for individuals. The outline region acquired through image processing ensures that the generated hair strands fall neatly into the hair region. In the case of hair strands falling out of the outline region, weights are added on reduced at the interconnected masses in order to move the strand back into the hair legion. The lines extracted by image processing serves as guide-lines directing the hair strands to point in the desired direction. Through this algorithm, hair model with close resemblance to the individual can be achieved. This realistic hair model can find many applications in the generation of synthetic humans and creatures in movies, multimedia and computer game productions.
