He then applied "unsharp masking" which, belying its name, increases image sharpness by bringing forth features that are otherwise too faint to see.

然后他利用钝化掩模图像增益法将其显著的地去隐藏掉，增强了图像的清晰度，使那些过于暗淡而无法看见的区域可以显现出来。

In self-organization freeform reconstruction method based on triangulation, each pixel of an image is taken as a bion of self-organization system, and each bion and its two neighbors constitute a triangular surface patch, then this bion adjusts its state in order that the triangle element satisfies the Lambertian reflectance model.

基于三角片化的自由曲面自组织重构方法将图像中的每个象素视为自组织系统中的生命单元，每个生命单元与其相邻的两个单元组成一个三角片，该生命单元调整自己的状态，使其与邻域单元构成的三角片按朗伯反射模型满足原始灰度图像的要求。

This method is that we first threshold image from the image, then we apply fuzzy distance transform to get fuzzy distance image, and finally, we use the watershed algorithm to apart conglutinant or overlapped grain.

该方法首先对颗粒图像进行二值化，然后对图像作模糊距离变换得到模糊距离图，再利用分水岭算法将粘连或者部分重叠颗粒分离。

The split between the two groups can hardly be papered over.
