Scanner

Extract a document from an image using opencv.

The scanner class provides some functions to extract a document (a piece of paper, Whiteboard, photo, ...) from an image. It does edge detection on the input image and transforms it to a 2-dimensional document. It also does some adjustments, like brightness and contrast.

The main.cpp is a simple demo/test application. To use the scanner class, copy it in your project. The functions should be self-explaining.

The class is aimed to be used in an Ubuntu SDK app with a live preview of detected edges when using the camera. This is work-in-progress.

Feel free to test and contribute, this code is far from perfect.
