i have built a patch (jit) to detect direction of movement in front of

now i want to calculate the energy/speed of motion.

s = [(last float value)-(first float value)]* (-1)

t= (time of last float value) - (time of first float value)

> when does movement start/ end (by a threshold time gap between float/bang(?) )

Probably there is another way to solve this problem, but I'm too stupid!

Hi,
i have built a patch (jit) to detect direction of movement in front of
a camera (with cv.jit.lkflow).
now i want to calculate the energy/speed of motion.
x=s(t)/t
s = [(last float value)-(first float value)]* (-1)
t= (time of last float value) - (time of first float value)
is anybody good at math? ( : 

i need to know:
> when does movement start/ end (by a threshold  time gap between float/bang(?) )
> time in between 

objects that i have reviewed:
counter,  timer 

i don't get it.. ) :

You probably don't need the time if you've got a reasonably consistent frame rate.

Rather than multiply your difference by -1, consider just taking the absolute value instead: [abs 0.]

do you know a object that stores the values in a way, that the operations can be processed?

yeah, that's a good idea!
thank you.

calculate speed of changing floats & detect activity
