However, your example is not a valid connectivity matrix. The Image Processing Toolbox connectivity definitions do not allow you to say that a pixel is directly adjacent to another pixel that's two steps away, which is what your matrix implies.

If i am not wrong bwlabel allows only scalars 4 and 8. hi steve,

Is there a way of establishing custom connectivity
such as conn=[00100;
01110;
11111;
01110;
00100];?
If i am not wrong bwlabel allows only scalars 4 and 8.
