这是HARRIS1988年角点检测的原文。。。非常有参考价值(This is the original HARRIS1988 corner detection. . . Reference value)

针对滚动轴承早期故障特征提取困难的问题，提出一种基于参数优化变分模态分解的轴承早期故障诊断方法。首先利用粒子群优化算法对变分模态分解算法的最佳影响参数组合进行搜索，搜索结束后根据所得结果设定变分模态分解算法的惩罚参数和分量个数，并利用参数优化变分模态分解算法对故障信号进行处理。(Aiming at the difficult problem of early fault feature extraction of rolling bearing, an early fault diagnosis method based on parameter optimization variational modal decomposition is proposed. Firstly, the particle swarm optimization algorithm is used to search the parameters of the variational modal decomposition algorithm. After the search, the penalty parameters and the number of components of the variational modal decomposition algorithm are set according to the obtained results. The modal decomposition algorithm handles the fault signal.)

借鉴了主成分分析算法（PCA），利用matlab写成的窄带噪声发生，含噪脉冲信号进行相关检测。( It draws on principal component analysis algorithm (PCA), Using matlab written narrowband noise occurs, Noisy pulse correlation detection signal.)
