image-construction-by-fft-and-wt
傅里叶变换和小波变换重建图像的比较效果,这个程序可以用来实现四个要求:1、FFT和WT重建效果比较;2、通过改变小波来比较重建效果;3、通过改变分解层数来比较重建效果;4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR

Adaptintegral
辛普森公式的自适应积分:在整个积分区间使用相同的小步长 ,以保持整体精度。然而,实际应用中,函数的振荡起伏的情况处处不同,这并没有考虑到曲线的某些部分变化剧烈,需要比其他部分多加考虑的情况。而有些部分,曲线的变化缓和,因此可以采用大于平均值的步长 来进行积分。因此,引入一种能够在函数值变化大的区间采用小步长的方法是很有用的。这种方法,称为自适应积分。(Adapt integral based on Simpson integral)
