Parameterization

Good Morning All, I was wondering if there was a way to parameterize the boundary of a shape given x and y cartesian coordinates?
I was thinking of using the matlab interpft function to get x(t) and y(t) not just xt and yt so I can use it when finding the fourier transforms coefficients. Any suggestion are very much appreciated.
Thanks Mel

This is a duplicate of an earlier question (http://www.mathworks.com/matlabcentral/answers/11552-fourier-transform-of-2d).

You can use bwboundaries. It gives you a parameterized boundary -- (x,y) location is parameterized as a function of array index.
