So the “on” pixels have a range of 100-400, okay, I think I’m with you now.


Yes! sorry for the confusion.



 markdaoust:

One advantage to using 0 instead of 100, is that it’s easy to tell that zero is not in that valid range.
If you set the background pixels to 100, when you see a 100, it’s never clear if that’s a valid 100 or a background 100.
Another option here would be to add a valid [0,1] channel to the images so your network, then the fill value would matter less.


Both of those ideas make sense. Thank you for your help!!
