Dot tracking - smoothing lost frames

Hi guys,

I’m trying to track dots from an IR camera. I’ve successfully converted the dots to primitives with trace & facet, and found their centroid to get positional data, but I’m struggin gto ‘smooth’ out the data as the camera sometimes drops frames or loses sight of the dots briefly.

I’ve simulated this with some circle TOPs and level to recreate the ‘dropping’:

Does anyone know of a nice/fast way of filtering this data so that the result is more consistant? I’m sure there would be a way to script it properly but I’m new to python.

I got the centroid technique from here: There is some info there but it is not very clear.

Hi,

Look at the Lag CHOP to smooth out your data
