Oil Painting Stylisation of Multi-scale Visually Layered Images Based on Drawing Algorithms

Image-based oil painting stylisation is a popular non-realistic drawing research area. A multi-scale visual layered stylisation algorithm is proposed, simulating the artist's process from coarse to fine. Results show the brush flow is determined by the Voronoi sequence and tangent direction, combined with brush shape and height field for texture mapping. This algorithm closely mimics real oil painting and enhances hierarchical picture sense, highlighting features and details.
