The texture features such as direction and contrast of the image can be obtained from weighted projection statistics of primitive feature, which are more matched with human vision.

然后通过对基元特征进行加权投影统计，得到图像的方向性、对比度等纹理特征，这些特征可以更好的适应人类视觉特性。

The edge is the important feature that human vision recognizes image target.

边缘是人类视觉识别图像目标的重要特征。

Finally, based on the feature that human vision is sensitive to the local contrast, the image of linear degree of polarization was adopted to enhance the fused result.

最后，根据人眼对局部对比度敏感的特点，采用偏振度图像对融合结果进行对比度增强处理。
