Abstract: This paper designs a new brush rendering method, through adopting a Gaussian image pyramid to generate a series of reference images, using different brushes to paint layer by layer in order to simulate the rendering stages from coarser to finer. This method uses statistics method to determine the brush’s color and pixels’ eight-neighbor concept to control the direction of brush strokes. Experimental result shows that a photo can be transformed to aesthetic images by setting up different parameters.

Key words: Non-Photorealistic Rendering(NPR), statistics, brush stroke model, Gaussian image pyramid, eight-neighbor

摘要： 采用高斯图像金字塔生成多幅参考图像，使用不同大小的笔刷进行多层绘制，模拟画家由粗到细的创作过程，设计一种新的笔刷绘制方法。在每层绘制时，使用统计方法确定笔刷的颜色，运用像素8-邻域的概念控制笔刷的走势。实验结果表明，通过多个参数的不同设置可以将一幅照片渲染成具有一定风格的艺术图像。
