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。

Furthermore, the relaxation direction changes from inward for diagonal atoms to outward for median atoms shows there is a "round corner" phenomenon.

此外，弛豫方向由对角线原子的向内弛豫变为中线原子的向外弛豫，这表明“倒棱”现象的存在。

The stress of the crustal median layer is roughly the same direction as the deep layer.

在不同深度上表现出中、深部层应力方向较一致。
