  This paper presents an efficient method for generating and rendering
photorealistic hair in two dimensional pictures. The method consists of three
major steps. Simulating an artist drawing is used to design the rough hair
shape. A convolution based filter is then used to generate photorealistic hair
patches. A refine procedure is finally used to blend the boundaries of the
patches with surrounding areas. This method can be used to create all types of
photorealistic human hair (head hair, facial hair and body hair). It is also
suitable for fur and grass generation. Applications of this method include:
hairstyle designing/editing, damaged hair image restoration, human hair
animation, virtual makeover of a human, and landscape creation.
