Upgrade App scanner to similar to scanbot

We are looking for upgrading our current app scanner to behave similar to Scanbot app. Scanner should automatically Capture ,Cropping & Optimization by detecting the page boundary. The page will have boundary on all 4 side and scanner should detect the boundary, auto crop the scan image from boundary, enhance it to better quality. We will confirm order with freelancer only after if they shows us mock app having at least autocrop feature and there shouldn't be failure to auto detect and autocrop. Please find the attached video for Scanbot app
