一种绘画效果生成算法

Method for generation of painting-like artistic effect

图像的绘画效果由平滑纹理,保持并加强边角获得。给出一种鲁棒的由真实图像自动生成相应绘画效果的算法。算法根据图像的局部结构,自适应地调节滤波器的带宽与形状,来模拟画笔宽度和绘画技法。实验结果表明,算法的处理结果在视觉效果上接近绘画,并且对低质量的输入图像同样有效。

Painting-like artistic effects can be achieved from photographic images by filters that smooth out texture details, while preserving or enhancing edges and corners.A novel image filter is proposed in this paper to generate painting-like effects.By adaptively changing its bandwidth and shape to image features, this filter can simulate the size of brush and painting skills.A large variety of experimental results show that the output of the proposed operator is visually similar to a painting.The proposed operator is robust to degradations of the input image such as blurring and noise contamination.
