I want to connect the connect the center point to the five points(head, hands, legs) for the attached figure of a human. I have the center point and all the boundary points but don't understand the logic how to connect them. I know about convex hull and have tried that but it doesn't give me the desired output. I think these five points lie at the extreme radii. Is this concept right?? If yes, then how can i find the extreme radii of this figure. Any help will be greatly appreciated.

I'm not sure you attached the correct figure. In no way does it ressemble a figure of a human.

The figure is correct. However, it is not drawn by Matlab bwboundaries, thats why its not that much precise. Also dimensionality reduction is performed on this figure.

See Steve Eddins presentation to ICIP last month on new MATLAB capabilities.
