problems with accessing webcam output in c# application

i know this is most likely a duplication and i am truly sorry for that but most of the solutions i found was either +7 years outdated, bugged or consume so much memory

all i need is an efficient way to access the webcam to record and display to use it in a computer vision project to detect moving objects and such, with an HD output (using HD camera of course)

also if there is a library that would help with the computer vision that would also be great

any information, tips or experience would be highly appreciated, thanks in advance and have a wonderful day.
