Re: Thinning algorithm

[AGD]

Hi, 

Apparently Matlab has a command for the thinning proces. The format looks
something like this:

BW2=bwmorph(BW,'remove');

where 'remove' is a function that eliminates the interior pixels; something
similar to thinning. 
However this format does not work in Octave even though there is a bwmorph
command in the image package.

If someone has an idea about this then please give in your solutions.

Thanks
