need code for image thinning , use rosenfeld algorthm and stentiford algorthm

[EDIT: 20110819 12:16 CDT - merge duplicate - WDR]

need source code to implementation stentiford algorthm for image skeleton ....

[Information merged from duplicate]

how to implementation skeleton or thinning algorthm, use stentifor, rosenfold, zang and suen, hilditch

need source code and flowchar algorthm

Answer 1

[Image Analyst]

Never heard of it. Why don't you want to use the skeletonization capability built into bwmorph()?

Answer 2

[Walter Roberson]

Azriel Rosenfeld published a number of image thinning algorithms. You need to be more specific. See for example here

walter, http://cgm.cs.mcgill.ca/~godfried/student_projects/laleh_pat_rec/rosen_alg.html ...... maybe you can help me ... this link explain about rosenfeld algorthm and i dont know how to implementation in matlab ...

[Megah Putri]

im use ROSENFELD ALGORITHM 8-CONNECTED...

Answer 3

[Sean de Wolski]

doc imfilter

or if you're like me and don't like imfilter because it's evil

doc conv2

will take care of that algorithm pretty painlessly for you.

Cool. Now we have two dogs in your logo. What are their names?

I don't see how a convolution or imfilter can do a non-linear operation like skeletonizing, rank filters, or other morphology where you preferentially assign values. For example, an erosion is a local min - how do you do that with convolution?
