%?denoise1.m
%---本程序是基于WaveLab802平臺作的。
%---包括以下方法：
%?VisuShrink方法、SUREShrink方法、BayesShrink方法、AdaptBayesShrink方法、LAWMLShrink方法。
%---運行方法：
%?將某方法對應行的代碼前的“%”去掉，而其他方法前一律都加“%”屏蔽掉。
%?噪聲方差大小和小波可以自行設定

I=imread（‘lena.bmp‘）;%讀取圖像數據
n=length（I）;
figure;
imshow（I256）;%顯示原圖像

%產生噪聲圖像
theta_noise=20;%噪聲方差（可設為其他值）-------------------------------------------
noise=GWN2（length（I）theta_noise）;
Inoise=double（I）+noise;
figure;
imshow（Inoise[]）;%顯示帶噪圖像

%小波濾波器選擇
qmf=MakeONFilter（‘Daubechies‘8）;%Daubechies8小波（可設為其他小波）-----------------
L=5;%分解層數＝log2（n）-L
[InoiseNormcoef]?=?NormNoise2（Inoiseqmf）;%歸一化
