Does it still require you to press a button to tell it every single time it's pointed at a new sheet of paper?

I'm waiting for one of these apps to monitor a video stream from a camera and automatically determine when a new sheet is ready to scan.

I already have a mobile app that can find the edges of the paper, crop it, and OCR all its contents. But it still needs me there as a human to tell it "the page you're pointed at now is one you haven't seen before" when that determination should be far simpler than doing OCR.

I'm waiting for the day I can aim my phone or webcam and just flip through a bunch of pages and have it scan each one as it appears. It doesn't have to be super fast like Data from TNG or Johnny Five from short circuit, I just want to go from "flip, press, flip, press, flip, press" to "flip, flip, flip"
