%程序L8_5.m: LUM滤波器%
%对一幅加噪声的图像，实验LUM滤波器%
load lena
Subplot(221),imshow(X,map)

%将原始图像加入噪声%
X=imnoise(X,'salt & pepper',0.05);  %加入密度为0.05的噪声
Subplot(222),imshow(X,map)

%进行LUM滤波%
[Y_k3l6]=LUM(X,3,6,5);              %LUM函数在本范例中
Subplot(223),imshow(Y_k3l6,map)

[Y_k9l12]=LUM(X,9,12,5);
Subplot(224),imshow(Y_k9l12,map)
