Disappearing blob rectangles when leaving screen
Aug 11th, 2009, 3:32am  
Hello,

I currently have a blob detector in my code which marks each detected white blob with a green rectangle. This is working well, but whenever a target moves off the top or bottom of the camera view, the rectangle disappears AS SOON AS the top/bottom of the rectangle touches the boundary of the camera view.

This behavior does not happen on the side edges.

This is a peculiar problem, and is a bit of an issue as if I detect a large white blob, it will disappear with only a small movement up or down.

Has anyone else encountered this issue, or know how to fix it?

If you don't mind to post the blob detection part of your code, so we can see where the problem is.
