Scanning documents using a smartphone

Diplomsko delo se osredotoča na razvoj mobilne aplikacije za operacijski sistem Android, ki z uporabo računalniškega vida prepozna papirne dokumente in jih na pogledu kamere obriše. Algoritem prepoznavanja dokumentov smo razvili v programskem jeziku C++ z uporabo odprtokodne knjižnice OpenCV. Vhodne parametre algoritma smo objektivno izbrali na podlagi reprezentativne zbirke slik, ki smo jih zajeli. Razvit algoritem smo integrirali v mobilno aplikacijo na operacijskemu sistemu Android. Aplikacija omogoča skeniranje in shranjevanje dokumentov preko mobilnega uporabniškega vmesnika. Služi tudi kot odprtokoden primer integracije C++ OpenCV knjižnice z operacijskim sistemom Android.This thesis focuses on the development of a mobile application for the Android operating system, which employs computer vision to identify paper documents and outline them in the camera view. We developed the document detecting algorithm in the C++ programming language using the open source library OpenCV. We objectively determined the input parameters of the algorithm based on a representative set of images that we captured. We integrated the developed algorithm into a mobile application on the Android operating system. The application allows the scanning and saving of documents through a mobile user interface. It also serves as an open source example of integrating the C++ OpenCV library with the Android operating system
