SIFT (scale invariant feature transform)

基非下采样的Contourlet变换的图像融合，要放到NSCT工具包中执行(Under the base of non-sampling Contourlet transform image fusion, to put the implementation of the toolkit NSCT)

里面有些常用的数值程序，如线性方程组的求解，插值，常微分方程的数值方法等等。(Inside some common numerical procedures, such as linear equations, interpolation, ordinary differential equations, numerical methods and so on.)
