Hi I have the following code and have some output as follows:
I =
0 1 1 1 1 1 0
1 0 0 0 0 0 1
1 0 1 1 1 0 1
1 0 1 1 1 0 1
1 0 0 0 0 0 1
0 1 1 1 1 1 0
K>> boundary = bwboundaries(I,8,'noholes'); K>> boundary
boundary =
[19x2 double]
[ 7x2 double]
here is two boundary, I need to know how to determine which boundary is interior, Here [ 7x2 double] is in interior region of [19x2 double]. How to determine that easily?
Can anybody help?
Thanks

>> [B,L] = bwboundaries(I,8,'noholes')
B =
[19x2 double]
[ 7x2 double]
L =
0 1 1 1 1 1 0
1 0 0 0 0 0 1
1 0 2 2 2 0 1
1 0 2 2 2 0 1
1 0 0 0 0 0 1
0 1 1 1 1 1 0
>>
B{1} -> label 1 (L == 1)
B{2} -> label 2 (L == 2)
EDIT 2
>> [B,L,N,A] = bwboundaries(I,8,'noholes')
B =
[19x2 double]
[ 7x2 double]
L =
0 1 1 1 1 1 0
1 0 0 0 0 0 1
1 0 2 2 2 0 1
1 0 2 2 2 0 1
1 0 0 0 0 0 1
0 1 1 1 1 1 0
N =
2
A =
(2,1) 1
>> full(A)
ans =
0 0
1 0
Having label 2 (number row A = 2) inside label 1(column number 1of matrix A)

You could also do an
Ibwnoholes = imfill(I,'holes');
which will fill the holes and then that boundary won't show up.
