I'm using MOG2 background subtraction with the default settings and what I'm assuming is noise in the video feed gets registered as foreground. I've eliminated much of the effects of this using a slight initial gaussian blur and also bhy applying a couple of morphologies after the mask is created, but I'm wondering what the best approach is to this.
Here's what a small piece of the RAW video looks like (NOTE: it may appear zoomed in when you play it) https://drive.google.com/file/d/0B5KsSamzM9xAazZ6YzJRa1Zubzg/view?usp=sharing
