The discrete curvature arithmetic was used to extract feature points, which the curvature expression contains Gaussian nuclear function and chooses appropriate discretescale factor.
提出用离散曲率法提取特征点，曲率表达式包含了高斯核函数曲线，选用了合适的离散尺度因子。

We concluded that the patterns mechanism is best-suited to small-scale transformations on discrete, individually selected model elements.
我们推断，模式机制能够良好地适应于对离散的、单个选择的模型单元进行小范围的转换。

Optimization also involves techniques for solving large-scale, discrete, nonlinear, multiobjective, and global problems.
