As Andreas explained:
x = hx/hw
y = hy/hw

hx,hy,hw are not unique, they are defined up to a multiplicative constant factor.
(hx,hy,hw)=(c.hx,c.hy,c.hw) for any constant c different from 0.
This is the usual homogeneous framework.

Thanks, but I can not understand how to compute hx from a given x.

can you explain?
