slow blob tracking

I’m finding the blob track top is very lazy in picking up blobs, even after tweaking the numerous parameters and using a bright background. Blobs will sometimes stay on a stationary spot and ignore movement within the frame. Am I doing something wrong or is anyone using it effectively? gtx660 i5 16gb ram.

I have the same card and CPU as you. These settings work for me.

thanks, will give it a try. I notice you’re not using the auto background detection so I wonder if that may be causing some issues.

absolutely. Background detection I found prohibitively slow and unnecessary
