一种基于局部方向尺度的各向异性扩散图像滤波方法
A Directional-Scale-Based Anisotropic Diffusive Image Filtering Method
摘要
Abstract
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.关键词
