Hi list,
I am trying to understand the coordinates I am getting from pix_blob. Example patch 03.movement_detection.pd assumes them to be normalized from 0-1. In my patch the values from pix_blob can easily become negative or go outside of the 0-1 range. This is especially the case when the blobs detected should become very large. Has anyone else discovered this?
This is on Debian testing with Gem 0.93.3 from the Debian package. I tested the same patch on OS X and there pix_blob does output in the 0-1 range reliably.
are the coordinates or the blobsize exceeding the 0-1 for you?
Yes, they do whenever the blob is getting very big or when the detection seems confused due to a large area of the image being "active".
For me the y axis is flipped for this patch.
You mean in 03.movement_detection.pd? Yes, I discovered this as well.
cheersio, P
