一个尺度不变特征变换(SIFT)算法例程代码

polar angle average for beamforming

说明：  针对数据分类问题，提出了基于极限学习机的分类方法，将数据样本分为训练样本和测试样本，并采用准确率指标进行评价。(Aiming at the problem of data classification, a classification method based on extreme learning machine is proposed. The data samples are divided into training samples and test samples, and the accuracy index is used to evaluate.)

采用SVM支持向量机，对5种故障进行分类诊断，程序可实现判断故障是否发生，并发生的故障类型进行诊断，根据故障数据分析故障类型，相比于传统神经网络算法具有更强的小样本数据分类能力。

说明：  本程序是一个采用背景差分的运动目标检测方法(This program is a moving target using the background difference detection method)
