I'm using the hough transform to detect lines in an image. I have a mix of long and short lines, and would like to exclude short lines. The 'MinLength' paramater is working, but I'm struggling to determine the units of this parameter. I would like to set it using knowledge of the scene I have to be physically meaningful.
My assumption is this in pixels, but I haven't been able to verify that experimentally.

Yes, they are in pixels.
