curvature calculation

Started by Unknown November 5, 2001
I have an image which i had smoothed using Gaussian smoothing
technique. I had also detected the edge of the object in the image.
Next, I would like to calculate the curvature of the edge. How can
do this using Matlab ? anyone got any idea ?? thanks..

Hi,
There is no specific tool for that. A good approach is
to fit a polynomial to the detected boundary(use
'polyfit') and than calculate its curvature.
