texture gradient

Natural factors include climate, vegetation, edaphic factors, terrain, geological and hydrological factors. However, the main factors include rainfall, the degree of vegetation coverage, the soil texture, the terrain gradient and the ditch density geological lithology.

其中自然因素包括气候因素、植被因素、土壤因素、地形地貌因素、地质因素及水文因素，但起主导作用的是降水、植被覆盖度、土壤质地、地质岩性、地形坡度和沟谷密度等；

Furthermore, since the image similarity is derived from image statistical features rather than original grey, texture and gradient features, this method is robust to low calibration precision.

此外，由于采用统计而非原始图像特征度量特征相似性，方法具有对辐射、几何配准精度要求较低等优点。

Firstly, the algorithm establishes a template, including the information of color, texture and edge gradient.

该算法首先建立目标模板，提取颜色、纹理、边缘梯度等多维特征，并建立相应的特征矩阵。

The annealing after hot rolling can weaken the orientation intensities of a-fiber texture of hot rolled sheet but strengthen the relative orientation intensities of y-fiber texture, lower texture gradient and promote the same oriented grains to distribute dispersively.

由于热轧后退火能显著弱化热轧板的α纤维织构，提高Y纤维织构的相对强度，显著降低织构梯度，提高各取向晶粒分布的均匀性。
