I am trying to generate the following “effect” from a basic shape in MATLAB:

But I don’t even know how this process is called. Let’s say I have an image containing the brown shape, what I want is generate the contours outside of it, that get smoother as they get bigger.

Is there either a name for this effect, a function to do this in MATLAB or an algorithm that does it from scratch?

thanks

    I think you are looking for bwdist.

    The image you are displaying looks like the positive part of a distance function from the boundary of your shape. You can perform this easily in Matlab using the examples on the aforementioned manual page.
