I have nothing to do with image processing (that's what I used to think!) as its' traditional meaning. I am trying to model the propagation of some burning material using a cellular automaton. The conventional approach was based on neighbouring propagation but the new idea is based on the heat transfer rate, which means the distance matters as well. I think the transform feature could be the key to a massive code simplifications!!! Thanks again and I would be grateful if you let me know of any reading references for CA design in MATLAB. Cheers, Mehdi,UCD,Ireland Hi Steve,

It seems like some application of bwdist should be able to do this. Any advice? Example: 1 0 1 0 1 0 0 0 0 0 1 0 1 0 1 Should yield 0 0 0 0 0 0 0 p 0 0 0 0 0 0 0 With p = path length = 1 Thanks in advance Hi,

I am trying to find the length and location of the shortest path between objects. It seems like some application of bwdist should be able to do this. Any advice?
Example:

1 0 1
0 1 0
0 0 0
0 1 0
1 0 1

Should yield
0 0 0
0 0 0
0 p 0
0 0 0
0 0 0

With p = path length = 1

Thanks in advance

This would be helpful to binarize images in complex natural scene images.. Hi Steve,
