Blob Tracking Performance

Hi All :slight_smile:

I’m working on a project that requires some audio triggering when people walk into areas in a space and its been working ok in 99 but the blob tracking slows down TD a lot (running at 12-13fps) and when I have 3+ blobs it often crashes :confused:

I looked online and people were talking about changing the mode of the blob track but that seems to have been removed in 99 or is there something I’m missing?

I rebuilt the project in 88 and its running at 60fps without any issues using the “connected component” Method so I might end up using that if the mode cant be changed in 99.

Thank for the help :slight_smile:

the question would be why do you need blob tracking?
drop the input video down to a low res grid of pixels that approx equals the number of areas you have. use video differencing to check if the there is a change.
if there is enough change in a pixel than trigger the corresponding audio.

Cool thanks for the tip, Ill see if I can work out the difference bit :slight_smile:

I used blob tracking more because I was able to make it work :stuck_out_tongue: but what you have suggested sounds like a much better solution.
