Blob Detection Tweaks

Postby Dara.smith » Wed Feb 13, 2019 1:05 pm

Hello TDers
So I,m looking into blob detection for a project at the moment.

First of all is there and easy way to get the life of a blob , to see how long its been alive.

Second is the touch implementaion of Blob detection or are the better implemtaions that can be used in conjunction with Touch (EG Open CV)

Thirdly . Thank you.

If you open Help->Operator Snippets->TOP->Blob Track you can see some examples how to work with the Blob Track TOP.

If you place an Info CHOP to read out the Blob Track TOP operator you'll see some extra channels of information per found blob. You could use these to start/stop a Timer CHOP whenever a blob is found.

I don't really understand your second question, is there missing a word perhaps?
