基于GPU加速的冲击滤波图像风格化绘制算法
|
摘要
本文提出基于结构张量引导的冲击滤波处理的图像抽象化绘制算法。算法以图像结构张量的特征向量值作为导向向量,对输入图像进行冲击滤波,从而获得具有结构张量场方向特征的风格化图像;本文同时提出运用GPU的并行计算能力,实现对输入图像及视频的具有类梵高流线风格的实时渲染及绘制。实验结果表明,该技术能有效生成具有类梵高流线风格的抽象化图像。
This paper presents a two-dimensional image stylized rendering algorithm based on structural tensor guided shock filtering. The algorithm takes the eigenvector value of the image structure tensor as the steering vector and impulsively filters the input image so as to obtain the stylized image with the directional characteristic of the structure tensor field. At the same time, this paper proposes to use the parallel computing power of GPU to realize the input image and Real-time rendering and rendering of video with Van Gogh's streamlined style. The experimental results show that this technique can effectively generate abstract images with Van Gogh's streamlined style.
