Hi,
I would like to know if it is possible to create a ROI on a current figure.
x=[1 2 3 4 5 6];
y=[7 8 9 10 11 12];
plot(x,y)
Now i would like to define a ROI, is it possible to use roipoly
I='Figure 1'
r=[-20 20]
c=[-20 20]
BW=roipoly(I,r,c)
cheers
nicolas

No. I has to be an image, not a string. And r and c must have at least three points - that would be a triangle. As you have it, r and c define a line, not a polygon.

It sounds to me like you should be working in the dual space from voronoi, namely the delaunay triangulation.
