Edge-preserving filters have been extensive used to image artistic stylization

but most of the existing filters can only generate cartoon-like style and can do nothing about the painting styles with clear brush stroke shape. Based on kuwahara filter

the paper proposes a multi-scale anisotropic kuwahara filter to generate some painting styles with obvious brush stroke shape. To simulate the painting techniques

saliency is used to control the size of the filter kernel and can produce strokes with rich geometrical scales. Based on the multi-scale anisotropic kuwahara filter

we also propose an artistic rendering framework for video stylization

which can keep frame-to-frame coherence well and automatically convert video into gouache or oil painting effect. To produce brush strokes a thick and layered feel

bump mapping is used to produce the stroke touch effects. The edge tangent vector field map

edge gradient magnitude and image saliency are combined to control the bump mapping

which can simulate the "impasto technique" well in oil or gouache paintings.
