sucess_in_fdct
本程序是一幅512*512的lena.raw图像进行快速DCT和其逆变换,整个程序均调试通过,是在C语言环境下编写的,在整个关于快速DCT的源码中,本代码可以说是集大成者,很值得一看。(This procedure is mainly of a float or double type of data, rounding, the float data can be positive or negative, can be, take the whole principle of rounding.)

adtive_feature1
以python语言为平台,对机载激光雷达原始数据Las格式和txt格式进行读取,并根据信息熵确定维度特征计算的最佳邻域半径,最后计算得到最佳邻域半径和最佳维度特征值(Based on Python language, the Las format and TXT format of airborne lidar raw data are read, and the optimal neighborhood radius is determined according to the information entropy. Finally, the optimal neighborhood radius and the optimal dimension eigenvalue are calculated.)

白平衡方法
采用色温估计法做的白平衡操作,之前是打算用到水下处理的,当然这个算法和PS的白平衡比有点LOW,可是这个能够matlab,有一定用途(The white balance operation using the color temperature estimation method was intended to be used underwater. Of course, the white balance ratio of this algorithm and PS is a little LOW, but this can be used in matlab.)

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)
