Now that I have a Pi5 I wanted to test some Computer Vision.
Been on my to do list for decades and I try every few years on Pi's.
A real pain to install Tensorflow, it needs X which needs Y which needs Z etc.
Tried many other ways that failed, the old Pip3 install methods don't work etc.
I had already tested Processing and was happy with how less slow it was than the last time I tested Java stuff on Pi's.
A bit of a search found this

A few minutes to install the library, finding a USB webcam and my face had a green box around it.
The quickest way ever to try OpenCV on a Pi5?
No compiling from source or missing libs, it just worked.
Probably not the fastest face recog but it sure was the easiest to get running.
And not much code![:D]( "Very Happy")
All I want to do is estimate and make a BVH pose from a single image, can this do it?
