Then we define the boundary strength function and the feature boundary of each patch, to construct a deformation contour on the patch's boundary.
然后定义分割片的特征边界和边界强度函数，用以表示各预分割区域边界上的形变模型；
At present, the CAD system always USES hybrid representations of feature representation and boundary representation in order to take advantages of both representations.
目前，在CAD系统中，一般采用特征表示和边界表示的混合表示方法，以充分利用两种表示法的优点。
We proposes to use the quadrant-mean filter to smooth the noise in the feature while alleviating the boundary effect of the features.
为去除特征中噪声的同时保持特征中的边缘，提出四分均值滤波器对特征滤波。
