Finding radius by fitting circles to partial lines
显示 更早的评论
Hello, I am trying to find the radius of circles from images which contain only a portion of the circle image, like this: http://postimage.org/image/hs9wbu3fv/ is anyone familiar with how to do this, for instance using Hough transforms? Thank you,

Only the radius? You already know where the center is?

Anyway, you'll find lot's of circle detectors on the FEX.
