David G.Lowe的SIFT算子在Matlab环境下的实现，尺度不变的特征提取，并对两幅图片的特征点进行匹配，运行前要把siftWin32文件放在Matlab的win目录下，具体请参照README。默认为输入为灰度图像，要处理彩色图片请先转灰度rgb2gray() (The realization of SIFT operator David G.Lowe in the Matlab environment, the scale invariant feature extraction, matching and pictures of the two feature points, the siftWin32 file in the Matlab win directory to run before, please refer to the specific README. The default is the input for the gray image to color image processing, please turn gray by rgb2gray ())

把HHT和神经网络结合起来，识别出是否故障。对于HHT变换，这里用到的是它的IMF分解，然后用能量理论来判别哪些模组是虚假分量，哪些是是真实分量。对于EMD分解后的谱进行特征提取 ，利用的理论基础就是模糊熵。计算出真实 分量的模糊熵，作为输入层；输出层为两个神经元，为0（故障 ）1（正常 （正常 ）判别该信号是否出现故障。(The combination of HHT and neural network to identify whether the fault. For the HHT transform, here is the use of its IMF decomposition, and then use the energy theory to determine which module is false, which is true component. The theoretical basis for the feature extraction of the spectrum after EMD decomposition is fuzzy entropy. The fuzzy entropy of the real component is calculated, as the input layer, the output layer is two neurons, which is 0 (fault) 1 (normal) to determine whether the signal is faulty.)
