title: How to detect curves in a binary image?
body: <p>I have a binary image, i want to detect/trace curves in that image. I don't know any thing (coordinates, angle etc). Can any one guide me how should i start? suppose i have this image <img src="https://i.stack.imgur.com/KPYPV.jpg" alt="enter image description here"></p>
  
  <p>I want to separate out curves and other lines. I am only interested in curved lines and their parameters. I want to store information of curves (in array) to use afterward.</p>
