I have $21$ joints (each joint has $2$ coordinates $(x,y)$). I would like to calculate average value to get center of all joints. And then normalize the original coordinates.
How can I calculate average and normalize?

2Just do the component-wise average. What kind of normalization do you have in mind? What should the maximum value / boundary be? – Matti P. Mar 18 '19 at 11:35

1my coordinates are 0-255 on image space. For component-wise average, you mean the mean value? – Dennis Thor Mar 18 '19 at 11:40

1yes, that's what I mean. If you want to normalize the valus, you obviously need to multiply all the values by some constant. In this case, the constant is equal to $255/max$, where $max$ is the maximum value. – Matti P. Mar 18 '19 at 11:44

1What do you mean by "joint" ? A vertex of a broken line ? – Jean Marie Mar 18 '19 at 12:19

Yes, like the vertex points on an image plane. – Dennis Thor Mar 18 '19 at 12:31
