flickering blob tracking

General TouchDesigner Discussion

Hi all,

I’m trying to use the blob track TOP to track people using kinectV2 and project an image in the location of the person/blob. I’m using the kinect’s IR input and I apply some filtering using the level top, but I had two issues:

1- the blobs keep flickering and as a result the image is not stable at all. Any suggestions for this?

2- Tracking Distance: The kinect IR input (after filtering using Level Top ) can only detect very close people (1 meter). How can I use the known kinect range and blob track people?

3- how can I blob track people accurately using this Blob Top?

thanks,

Hi lulu, do you have an example file?
Is there a reason you’re using the IR texture and not the player index as an input to the blob tracking? Another possibility may be to align the tracking data from the Kinect CHOP to screen space to get similar data from the Kinect SDK’s skeletal tracking.

If this is top down tracking, you may want to look at this:
