After comparing the two type of tests,we came to some conclusions.The tests based on binomial test can be regarded as some kind of permutation tests under certain definition of "permutaton".If the tests are related to statistics,then whether they can be viewed as permutation tests depends on if the value of the probability,p,is known where p is the population parameter in the null hypothesis.For tests like Kolmogorov goodness-of-fit test,since the statistics is calculated based on empirical distribution function,hence no matter how we repermutate the observations,the order statistics is the same.This kind of tests can't be regarded as permutation tests.

我们得到的结论为：在一般的无母数检定中，如果检定与binomial test相关，基本上都可以视作排列检定的一种；与卡方检定相关的检定，基本上和p值已知或是未知有关，这个p值为原始假设下所要检定的母体机率值；其他检定如Kolmogorov goodness-of-fit test，由於统计量的值是根据empirical distribution function决定，而不论如何重新排列样本，其顺序统计量都不变，所以无法视为一种排列检定。

For the automatic scaling and analysis of the ionospheric parameters, a method based on the empirical orthogonal function analysis of the ionospheric electron density profiles is proposed in this paper. This method is applied to the measured ionograms of CADI (Canadian Advanced Digital Ionosonde), which is set up at Beijing Space Environment Observation Station (403°N, 1162°E).

In the video segmentation method based on DEMD, the intrinsic mode function with the lowest frequency is discarded and a simple and effective motion compensation method is adopted. As a result, the video segmentation method is no longer sensitive to abrupt change of luminance, object motion in shots, motion and zoom in/out of cameras, so that the precision of detecting shot boundaries is improved.

基于DEMD的视频分割方法除去视频帧中反映图像内光照分布与能量的最低频率固有模态函数(intrinsic mode function，IMF)分量，并选择一种简单有效的运动补偿方法，解决了传统基于直方图方法对光照突变、镜头内物体运动和镜头运动及拉伸的敏感问题，减少了镜头边界识别的误检率，在保证召回率不受影响的前提下提高了视频分割的精确度。

First, we divide the input signal into four non-uniform subbands via discrete wavelet transform. In addition, a nonlinear Teager energy operator is then utilized into each subband signals. We show that the TEO can decrease the influence of noise on subbands significantly. Besides, the other advantage is suitable for the result of subband auto-correlation function.

首先，离散小波转换将输入讯号分成四个不均匀大小的子频带，而在每个子频带上采用一种非线性的Teager能量运算(Teager Energy Operator， TEO)以有效抑制噪音在各子频带的影响，而另一优点就是有助於子频带自我相关函示(spectral auto-correlation function， SACF)之结果。
