dual-tree
首先将非平稳的故障振动信号进行双树复小波包分解，得
到不同频带的分量；然后对每个分量求其峭度值和相关系数并进行比较；最后选取峭度值和相关系数较大的分量
进行软阈值降噪和双树复小波包重构，即可有效地消除振动信号中噪声的干扰，同时保留信号中的有效信息即实
现了故障特征信息的提取。(In view of the above situation, a new fault diagnosis
method is proposed based on dual-tree complex wavelet packet transform and threshold de-noising. Firstly, the
non-stationary fault signal is decomposed into several different frequency band components through dual-tree
complex wavelet packet decomposition. Secondly, Kurtosis and the cross-correlation coefficient of each
component are obtained and compared. Due to the kurtosis reflecting the signal variations, if the kurtosis value is
bigger, the degree of the change of signal is bigger too. The correlation coefficient can reflect the proximity
between the component and the original signal at the same time, the correlation coefficient is bigger, the more
similar with the original signal. Finally, the components that have a bigger value are chosen to be de-noised by a
soft threshold and reconstructed by dual-tree complex wavelet packet transform. The noise interference was
eliminated effectively, and the effective si)

HumanMotionDetection
从人流统计的实际工程出发,实现了基于计算机视觉的人体运动检测及跟踪系统,采用“差影法”滤掉静止帧,使用自适应的一阶递归滤波及帧差法提取运动区域,并通过数学形态滤波的开运算和闭运算改善运动区域提取效果。实验结果证明本运动跟踪方案处理简单高效
、抗噪能力强,可以完成复杂背景下运动目标的实时性检测与跟踪。(Flow statistics from the actual project, the realization of computer vision-based human motion detection and tracking system, using )
