A Smartphone Application for the Creation of Legal Document Photographs

Legal document photographs have to conform to the requirements stated in the ICAO photograph guidelines. Due to the average individual being unfamiliar with these requirements, legal document photographs are normally taken by a professional photographer. This research is focused on offering an alternative to the photographer with a smartphone application. The application detects the conformance to all requirements using modern image processing and computer vision algorithms. The user is informed to which requirements the image does not conform and is instructed by on-screen gestures, text and vocal messages.
