Object Detection and Tracking on Android

I am about to embark on a bit of a journey into Computer Vision. My Goal is to track a single (but changeable) Object in the CameraPreview of an Android Phone. I have done some research online about what different methods there are to achieve this, I found a lot of videos showing that it works, but sadly i didn't find any examples published on github. From what I saw and read i would implement a MOSSE tracker because it seems not to be too computationally expensive (which would mean i could run it on a phone). Additionally i was thinking i would like to combine this with a detection network which i would run sparsely on some of the Frames - depending on how much cost is asociated with that. This I would do to correct any accumulated tracking error of the bounding box which i would like to be as accurate as possible. That said this is only a plan not having done any work with CV algorithms before. I would appreciate any tips on performance of the different options out there and/or any links to some ressources/sample projects that you know of.

The main question I have is: Is what I am thinking possible or are there any major hurdles that I can not see yet that would prevent me from doing this? Thanks for your help

i'd think, you're on the right path already.

tracking does not care, what it tracks (so it's interchangeable), but it needs an initial rectangle / detection (so there we're at the object detecton part. maybe look at the dnn detection example for the latter ?

then, unfortunately, the tracking module is not part of the main opencv android SDK, to use it, you'll have to rebuild from src (with the opencv_contrib modules), see here for that

Thank you for the quick feedback :D I will checkout the resources and check in once i have other or more specific questions.
