Identify curves in binary image
I have a binary image in which I would like to detect curves and output the coordinate pixel positions of the curves. The image is a noisy one and I would like to detect the two curves that run horizontally.
I am using MATLAB to perform image analysis. It will be great if you can provide me some hints towards identifying these curves.
An example picture:
Solution
Use a canny edge detector. But, in order to make it work well, you'll have to read about the parameters that go into it, and "fiddle" with them. I expect Canny edge detection to do pretty well on this data set.
