Hello

I wanted to ask after saving each one of the created boundaries in a variable how can I save them as an image array ?

Following this tutorial I can plot them

http://www.mathworks.com/help/toolbox/images/ref/bwboundaries.html

But there is not any hint how can I store them in an array.

Thank in advance

Use bwperim() to get an image of the boundaries. Then save that with imwrite(). If you really want to use bwboundaries, you have to create an image (full size black image) then go down the list you got from bwboundaries, setting each coordinate to white.
