暂时只支持jpeg2000支持的 cdf97 和spline53

可以这样来测试：

x=imread( E:\\study\\jpeg2000\\images\\lena.tif )

％ see the decomposition coefficients

y=wavelift(x, 1, spl53 ) using spline 5/3 wavelet

figure subplot(1,2,1) imshow(x) subplot(1,2,2) imshow(mat2gray(y))

％ see the reconstruction precision

yy=wavelift(x, 5) using cdf 9/7 wavelet

ix=wavelift(yy,-5) inverse

sum(sum((double(x)-ix).^2))

-only temporary support jpeg2000 support cdf97 and spline53 this can be measured Examination : x = imread (E : \\ study \\ jpeg2000 \\ images \\ lena.tif)% see the d ecomposition coefficients wavelift y = (x, 1, spl53) using spline 5 / 3 wavelet figure subplot (1,2,1) imshow (x) subplot (1,2, 2) imshow (mat2gray (y))% see the reconstructi on precision wavelift yy = (x, 5) using cdf 9 / 7 wavelet ix = wavelift (yy. -5) inverse sum (sum ((double (x) - ix). ^ 2
