说明：  ARIMA 模型是在平稳的时间序列基础上建立起来的，因此时间序列的平稳性是建模的重要前提。检验时间序列模型平稳的方法一般采用 ADF 单位根检验模型去检验。当然如果时间序列不稳定，也可以通过一些操作去使得时间序列稳定（比如取对数，差分），然后进行 ARIMA 模型预测，得到稳定的时间序列的预测结果，然后对预测结果进行之前使序列稳定的操作的逆操作（取指数，差分的逆操作），就可以得到原始数据的预测结果。(time series prediction ARIMA)

图像引导滤波，实现平滑滤波，图像细节增强、去雾霾！！！(guided image filtering img_enhancement img_smoothing img_flash img_feathering)

pitch=CorrelogramPitch(correlogram, width [, sr, lowPitch, highPitch]) computes the pitch of a correlogram sequence by finding the time lag with the largest correlation energy. (pitch = CorrelogramPitch (correlogram. width [02:04 lowPitch. highPitch]) computes the pitch of a correlogra m sequence by finding the time lag with the large st correlation energy.)
