When I need to threshold small noise or other stuff that I don’t need to track it’s easy right? Yep! Just change minimum blob size in pixels by attribute [threshold].
But how to make also in the same time threshold “bigger than” objects?
Just I have situation where I know a needed size range!
For this time only one thing came into my head – unpack all data and compare area of blobs…but I use list “on the fly” and hope
that anyone of Jitter community have a beutirfull and simple idea!

Many thanks for your time!
Cheers

but working on lists (after jit.iter) can be easier.
i usually make it a list store in a coll and query mass, index etc.

it is up to a point, in the end both r just A2D convertors. the “shit in
shit out” rule applies here. you might get better answers if you explain a
bit what you want to do with your video. do you want to record, manipulate,
apply as texture, computer vision, buffer…
