Hi all, For the following image;
How can I get the vertices (which are highlighted by orange dots) of each Voronoi polygon of the following Voronoi diagram?
The picture is from the Internet. It is just for illustration.
Any suggestions for code to get these vertices?

How you got this image? YOu plotted using inbuilt function? Or you have a image and you want to get points from the image?

x = gallery('uniformdata',[1 10],0);
y = gallery('uniformdata',[1 10],1);
[vx,vy] = voronoi(x,y);
plot(x,y,'r+',vx,vy,'b-')
axis equal
(vx,vy) are the vertices you want.

How do I get the co-ordinates of each polygon separately? I tried adding a for loop which defines the number of regions, but I am still getting the vertices of the last region. Also [vx, vy]=voronoi(x,y) provides all the coordinates, I want for the individual regions. Can you help me on this?
