I am looking for a description of algorithm which allows me to detect key turning points on the road amongs a set of all given points.
I've ilustrated my problem on the below image:
Green spots: those are the starting and ending point of a route.
Blue spots: those are the key points which should be detected by the algorithm.
Red dots: This is the data about the road that has been driven.
Could someone point me to the algorithm name or publication that deals with this problem?
Thanks in advance.
