If
The first point is **P1 [x1,x2,...,xn]**
The second point is **P2 [y1,y2,...,yn]**
so ，the Euclidean space distance from P1 to P2 is
**d(P1,P2) = sqrt ( (x1-y1)^2 + (x2-y2)^2 + ... + (xn-yn)^2 )**
so , in the face recognition field , for example , in many open source ，
every point have x coordinate value and y coordinate value ,
I think it is ,
The first face is **P1 [(x1,y1),(x2,y2),...,(xn,yn)]**
The second face is **P2 [(a1,b1),(a2,b2),...,(an,bn)]**
so ，the Euclidean space distance from P1 to P2 is ________________________________ ?
the result is too complex , even is unsolvable .
I don't know if I have a problem with my understanding ?strivingMon, 04 Dec 2017 22:01:04 -0600http://answers.opencv.org/question/179732/
