有一个问题:
a =
0.5447 0.5436 0.5431 0.5440 0.5461 0.8472 0.5466 0.5457
0.5461 0.5452 0.8442 0.5441 0.5452 0.8461 0.5464 0.5464
0.9495 0.5488 0.9476 0.5467 0.5469 0.5476 0.5484 0.5492
0.9510 0.5505 0.5493 0.5482 0.5480 0.9485 0.9493 0.5504
0.5481 0.5476 0.5466 0.5461 0.5464 0.5470 0.5474 0.5479
0.5450 0.5442 0.5436 0.5442 0.5457 0.5465 0.5462 0.5456
0.5445 0.5434 0.5432 0.5448 0.5473 0.5484 0.5474 0.5458
0.5448 0.5436 0.5434 0.5451 0.5479 0.5491 0.5479 0.5462
>> A=im2bw(a,0.8) %A中的数据,大于0.8的变1,小于0.8的变0;
A =
0 0 0 0 0 1 0 0
0 0 1 0 0 1 0 0
1 0 1 0 0 0 0 0
1 0 0 0 0 1 1 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
>> [L,n1]=bwlabel(A)
L =
0 0 0 0 0 3 0 0
0 0 2 0 0 3 0 0
1 0 2 0 0 0 0 0
1 0 0 0 0 4 4 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
n1 =
4
若a是个n*n*n的三维矩阵,矩阵中的数据也是0到1之间的数据,如何实现上述的功能?
A=im2bw(a,0.8)
[L,n1]=bwlabel(A) 这两个命令应该如何改成三维情况?
谢谢
