1·Then, the classification abilities of different local positions in the face were evaluated, and feature points were chosen at the positions with the strongest discriminating power.

然后对人脸不同局部位置处采样点的分类能力进行评价，选择分类能力最强的位置提取特征点。

2·By using DSP virtual discriminating method to distribute load, meanwhile optimize the system frequency output, can rapidly stable power supply fluctuations caused by uneven oil supplied.

采用DSP虚有差法分配负荷，在优化系统频率输出的同时，也能够快速稳定柴油机因供油不均引起的输出功率波动。
