add stabilization? #16

Closed gherkins closed 3 years ago

gherkins commented 4 years ago

how about adding position stabilization while already having a list of frames?
I'd think that'd be a great additional feature for a tracker, wouldn't it?

as seen in https://github.com/tawnkramer/CarND-Vehicle-Detection#3-stablization

hi, could you be more specific ?

gherkins commented 3 years ago

hey, maybe just return the average position of the last n:configurable frames...
That would make for a much smoother movement of tracking frames when displayed.

tdurand commented 3 years ago

what would be the method to compute the average position for moving objects ?

gherkins commented 3 years ago

i guess you'd have to feed a relatively short list of frames to prevent lagging,
but maybe implementing one of those would be worth a try: https://www.npmjs.com/package/moving-averages

tdurand commented 3 years ago

ok, yes but we can't do that as we are computing in real time, we just know the next and previous frame to perform tracking ;-)

gherkins commented 3 years ago

🤔 i thought that would make it fairly easy to keep the n last frames and output the moving average position instead of the actual exact position.

but of course you can do that on top of the tracking from outside...

thx anyway!

tdurand commented 3 years ago

yes, but you can't display in real time in this case... Don't get me wrong, you are very welcome to send a Pull Request will this feature added that we could enable as an extra feature
