common feature set

基本解释

Although all digital SLRs share a common base feature set as you move up the ranges you'll find more and more advanced features which may or may not be of importance to you.
尽管所有的数码单反都有类似的基本功能，但是随着你操作的进一步提升，你会发现更多进阶功能，虽然这些功能未必对你有多么重要。
In the scheme, a set of feature parameters are extracted from signal spectrum and constellation based on the differences between digital mixed signals and common digital modulation signals.
该方案利用数字混合信号与常用数字调制信号在信号频谱以及星座点的差异提取特征参数进行自动识别。
Besides common geometric measurements such as distances and angles, a new measurement of average curvature energy defined for boundary curve segment is included in the set to describe curve feature.
除了常见的几何测量（如距离和角度）外，提出了一种平均曲率能量的测量方法来描述边界曲线特征。
