Computing the discrete Fréchet distance in subquadratic time

PK Agarwal, RB Avraham, H Kaplan, M Sharir - SIAM Journal on Computing, 2014 - SIAM
The Fréchet distance measures similarity between two curves f and g that takes into account
the ordering of the points along the two curves: Informally, it is the minimum length of a leash …

Approximating the Fréchet distance for realistic curves in near linear time
