Description: 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

行如下操作：去除图像的不均匀背景；用设置阈值的方法(thresholding)将结果图像转换成二值图像；通过成分标记(components labeling)返回图像中的目标对象属性，并计算目标对象的统计数字特征。-to rice. Tif images for example, introduces the morphology of gray image processing and analysis techniques, that the gray image proceed as follows : Removal of uneven background image; by setting the threshold value method (thresholding) will be converted into images results binary image; through the composition tags (components labeling) to image targets attribute, and calculate the statistics target characteristics.
