Implementing ridge detection

Question

I\'m trying to write a ridge detection algorithm, and all of the sources I\'ve found seem to conflate edge detection with ridge detection. Right now, I\'ve implemented the Canny

Answer 1

If anyone is still interested in this, here is an implementation of the ridges/valleys algorithm: C++ source code. Look for a function called get_ridges_or_valleys(). This implementation is a 3D version of the algorithm proposed by Linderhed (2009). See page 8 of the paper for the ridges/valleys algorithm.
