SIFT
- SIFT是由UBC（university of British Column）的教授David Lowe 于1999年提出， 并在2004年得以完善的一种检测图像关键点（key points , 或者称为图像的interest points(兴趣点) )， 并对关键点提取其局部尺度不变特征的描绘子， 采用这个描绘子进行用于对两幅相关的图像进行匹配（matching）。 目前， SIFT可以说是所有图像局部特征描述特征子 中最火的一个了。-SIFT was developed by David L

- 为保障安全与电力用户供电质量，基于并网逆变器的分布式发电(distributed generation DG)系统要求具备孤岛检测功能。针对被动式孤岛检测法检测盲区(non-detectionzone，NDZ)大、检测时间长以及主动式孤岛检测法影响分布式发电系统供电质量的缺点，提出了一种新的被动式孤岛检测方法。该方法利用小波变换从公共耦合点(point ofcommon coupling，PCC)处的电压信号及逆变器输出电流信号中提取特征量，再通过BP 神经网络进行模式识别来判断是否出现孤岛现象
