I want to detect motion in a quick way before tracking, will absDiff() (or cmpS() ) between 2 frames be sufficient to achieve this or should I consider something more? Pls keep in mind I’m completely new to vision processing and opencv 🙂
Thanks
There’s no quick and easy way. The method I’m trying is to build a background image over time, subtract the foreground which would be anything not part of the background and put a roi over the foreground object.
