In allusion to this question, in this paper, we proposed a method of image filter based on direction gradient.

针对这一问题，本文提出了一种基于方向梯度的图像滤波算法。

This paper presents a new adaptive multilevel median filter based on direction information measure to solve the contradiction between noise attenuation and image details-preserving (edge-preserving).

针对图像滤噪中滤除噪声和保护细节(边缘)的矛盾，本文提出一种新的基于方向信息测度的自适应多级中值滤波器。
