How can I measure the curvature of a 2D image?

I want to calculate the curvature of the attached image? Do you know any method that I could use?

Thanks!

Hi,

You could use Edge Detection methods from Image Processing Toolbox to find the edges in the image. You will recieve a binary image where 1s specify the edges. You can also get the points of the curve by reading 1s in that image and find curvature using one of the curvature functions.

Refer to the following link to find more about edge function

Refer to the following link for getting the curvature function of a 2D line
