01:53 finger563 anyone know how to properly save the alpha channel of the ofFbo?

04:19 dkadish_ Anyone know how to go about correcting that? I'm not quite sure where to start...

22:40 jedahan okey dokey who wants to help point me towards ways to undestand what parameters I should use to setup a kalman filter for a simple signal?
22:42 admsyn I can try to say things that might help?
22:42 admsyn he says with utmost confidence
22:42 admsyn what are you filtering?
22:42 jedahan the width of someones bounding box in a video
22:42 jedahan as a float between 0.0 and 1.0
22:43 admsyn alright
22:43 admsyn due diligence: I'm gonna guess a low pass / lerp isn't cutting it?
22:43 jedahan actually they might cut it now that I think of it
22:44 jedahan should try that first O_O
22:44 admsyn it's *definitely* the easiest
22:44 admsyn ofLerp all the things all the time
22:44 admsyn if it works
22:44 admsyn you won't get the predictive effect you get from kalman
22:44 * admsyn is pretty sure kalman does prediction
22:45 jedahan yeah there is a prediction step and then another step
22:57 jedahan hmm ofLerp might be enough

23:23 jedahan well, ofLerp would work, if we had the camera aligned in the same orientation as every human being
23:24 jedahan but since a vertical aligned camera would 'look bad' half of people's bodies are cut off and I just gotta pretend that they have a head and arms and figure out some other predictive stuff
23:24 jedahan -.-
