Alright, super new to opencv though I’ve dabbled with my own creations for vid surveillance.
So basic question one is on motion detection. One issue I have is the h264 feed from a rtsp cam is ever so slightly changing frames even though nothing is happening in that particular part of the frame, but its changing enough to “drown” real events if they’re small enough (for the threshold given).
Then I stumbled on some opencv code on stackoverflow that essentially did GaussianBlur on the frame first before subtract/absdiff/threshold … and look and behold much better performance(in terms of picking up the correct events). So the question is this:
- Is using techniques like gaussian blur “industry standard” for stuff like motion detection? Any other tricks I should know about in this regard?
Thanks :). (I got ton more questions, but dont want to wear anyone out:)).
