I'm working on a project that includes lane detection and tracking; I'm able to detect straight lines in image using HT; I'd like to know how to accurately detect and fit curved lines in an image. Thanks folks

Hi eric.My project is exactly like you but im using the b-snake rather than HT.Can I know how you removed the unwanted background such as trees and shadows from the road? What is suitable technique that you use ? I really hope for your reply.Tq

If you have the coordinates of the pixels, you could use polyfit to fit them to a polynomial.

Hough Transform can also be used for detecting curves:

Thanks a lot for your quick reply J, I've read the paper but frankly speaking it's been kinda difficult for me to derive a working code based on that paper within these days. Can u direct me to a working code for curve fitting? not necessarily based on HT of course. the ones I hv can only detect straight lines and no curves!
