摘要：
1．applylut
功能：在二进制图像中利用lookup 表进行边沿操作。
语法：A = applylut(BW,lut)
举例
lut = makelut('sum(x(:)) == 4',2);
BW1 = imread('text.tif');
BW2 = applylut(BW1,lut);
imshow(BW1)
figure, imshow(BW2)
相关命令：makelut
2．bestblk
功能：确定进行块操作的块大小。
语法：siz = bestblk([m n],k) [mb,nb] = bestblk([m n],k)
举例
siz = bestblk([640 800],72) siz = 64 50
相关命令：blkproc
3．blkproc
功能：实现图像的显式块操作。
语法：
B = blkproc(A,[m n],fun)
B = blkproc(A,[m n],fun,P1,P2,...)
B = blkproc(A,[m n],[mborder nborder],fun,...)
B = blkproc(A,'indexed',...)
举例
I = imread('alumgrns.tif');
I2 = blkproc(I,[8 8],'std2(x)*ones(size(x))');
imshow(I)
figure, imshow(I2,[]);
相关命令：colfilt, nlfilter,inline
