扩散滤波全称也作相干增强各向异性滤波,是一项尺度空间的图像恢复技术,也是一种定向平滑的技术.与其他平滑技术相比,它具有最优的平滑特性和保持边缘特性.这种滤波方式能压制噪声、提高横向连续性、增强地震数据对层序体内部结构的成像能力.因此,图像噪声的过滤是数字图像处理的重要步骤.

The full name of diffusing filter is coherent enhancement anisotropic filtering, which is a image recovery technique in the scale space, and also is a technique of orientation smoothing. Compared to the other smooth methods, it has a big advantage of smooth and keeping edge characteristic. It plays a significant role in suppressing noise, improving lateral continuity and enhancing the imaging capability of seismic data. So noise filtering is an essential procedure in processing.
