Abstract: Combining vector-field-based hairstyling and sketch-based hairstyle curves,a method of interactive hairstyling with sketchy curves is proposed. By the method,three kinds of hairstyle curves and some hairstyle editing strokes are defined as the constraints of vector-field generation. The defined tools can be employed by users to control or modify hairstyles with their freehand drawing,so that a novel interactive mean is provided for hairstyling. Furthermore,an interpolation algorithm is used to simplify the vector-field computation,by wihich the real-time performance of interactive hairstyle generation is achieved. Experimental results show that the proposed method can be used to generate several hairstyles interactively.
