摘要 针对图像滤波去噪模糊边缘结构的弊端,提出了一种基于局部方向尺度的各向异性扩散图像滤波方法。该方法首先为图像中每个象素定义相应的局部方向尺度,然后利用象素的局部方向尺度在边缘附近或细小结构的小区域内进行小尺度扩散滤波,而在较大的均匀区域的内部则进行大尺度扩散滤波。实验结果表明算法比现存的各向异性扩散滤波方法在保持图像的细小结构和对象边缘方面具有更好的性能。 Due to image filtering often blurring the edge structure in images, a directional-scale-based anisotropic diffusive image filtering method is proposed. It defines a corresponding local directional scale for each pixel in the full size image firstly, and then uses pixel directional scale filtering the fine detail regions or the vicinity of boundaries with a restricted parameter while using a generous parameter in the homogeneous regions. Experiments results show that the anisotropic diffusive filtering method proposed has significant improvement over the current filtering methods in preserving fine details and sharpness of object boundaries.
