Abstract: Image based oil painting stylization is a popular research topic in the domain of non-photorealistic rendering.In this paper,we propose a novel layered oil painting stylization algorithm which applies multi-scale brushes to improve the quality of oil painting stylization.Considering the real painting procedure of artists,we adopt multi-scale brushes to obtain oil painting effects by successively combining layers where brushes of large scales to small ones are employed.In each layer,we use incremental Voronoi sequence and image tangent orientation field to create brush lines.Stylized oil painting brush strokes are synthesized by texture mapping according to brush shape and brush height field.Our method can simulate the painting procedure of artists.Compared with existing methods,better oil painting results are achieved where both structures from input images and details from synthesized brushes are exhibited.
