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
4．brighten功能：增加或降低颜色映像表的亮度。
语法：
brighten(beta)newmap = brighten(beta)newmap = brighten(map,beta)brighten(fig,beta)
相关命令：imadjust, rgbplot
5．bwarea功能：计算二进制图像对象的面积。
语法：total = bwarea(BW)
举例
BW = imread('circles.tif');imshow(BW);
bwarea(BW)ans =15799
相关命令：bweuler, bwperim......
