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

Description: 这是第一版的AsymPDC工具包。用来处理PDC，gPDC和iPDC有关内容。运行环境为Matlab,并且要求至少Matlab中预装了3个工具箱：控制系统，信号处理和统计工具箱。-This is the first public release of AsympPDC package. It deals with the asymptotic statistics for PDC, gPDC and iPDC.
AsympPDC runs under Matlab and is a practically self-contained except for requires routines from three Matlab toolboxes: Control System, Signal Processing, and Statistical.
It is not extensively tested yet. It was partially tested under Windows, Macintosh and Linux environments with Matlab version 7.0 and higher.
Please report any incompatibility to ksameshi[at]usp.br or baccala[at]lcs.poli.usp.br.
Additionally for cosmetic purposes, the pdc_xplot routine uses several Matlab users contributed codes: subplot2.m (modified old version of supbplot to control spacing between subplots), shadedplot.m (developed by Dave Van Tol), suplabel.m (for label and title plotting in subplot figures, by Ben Barrowes), suptitle.m (contributed by Drea Thomas, for adding title above all subplots), and tilefigs.m (for tiling figures for simultaneous visualization, by Charles Plum)

Description: a.阅读的图像img_1.tif，img_2.png的文件夹中，并
他们展示于一体，这两个数字分别。
（参考函数：imread, imshow, figure, subplot）
b.在matlab，观察从工作区中的图像信息面板
c.分别使用size, imfinfo,whos等功能获得的图像信息
d.添加标题的图像。 （参考函数：title）
Ë 。下面的代码实现的M文件编辑器
f=imread(‘img_1.tif’)
imshow(f)
set(figure(1), NumberTitle , off , Name , my first image’)
观察结果，并确定的功set()
f。保存img_1.tif目录“D：\ imagetest”。如果该文件夹不
存在，请首先创建这个新的文件夹。 （参考函数：imwrite）
-a. Read the images img_1.tif, img_2.png given in the folder, and
show them in one and two figures respectively.
(referenced function: imread, imshow, figure, subplot)
b. In matlab, observe the images information from the workspace
Panel
c. Use size, imfinfo,whos,etc functions to obtain image information
respectively.
d. Add title to the images. (referenced function: title)
e. Implement the following codes in the M-file Editor
f=imread(‘img_1.tif’)
imshow(f)
set(figure(1), NumberTitle , off , Name , my first image’)
observe the result, and determine the function of set()
f. Save img_1.tif to the directory “d:\imagetest”. If the folder does not
exist, please create this new folder first. (referenced function:
imwrite)
