Thread Subject: how to calculate curvature at each point on boundary of object in matlab

Hello

  I want to find curvature at each point on boundary of object in
order to find change in direction of boundary.


Can anyone help me.

Why not just compute it directly from the output of BWBOUNDARIES?

Thanks Matt for answering.

I have traced boundaries but don't know how compute curvature.
Please tell me how to compute it??
