I am trying to measure the line length of the blue lines shown in the image below. I have tried using various combinations of making it binary, auto threshold, using skeleton 3d, and other image altering processes to get ridge detection to properly read the lines, but I am having no luck. I always end up with ridge detection saying I have more blue lines than I actually do. Has anyone had any luck with a similar project that can point me in the right direction or is using a different method to alter the picture so ridge detection can properly work?
Any help is greatly appreciated!
