Office Lens like document scanning.

This project lays way to long on my hard drive. I sporadically code on this project since I do not own an Ubuntu Phone yet and have other projects. Feel free to take over development.

• scan an image using the camera (with live preview of detected edges)
• different filters, image rotation
• export/import from content hub

• a small C++ lib that does the processing using open-cv (see https://github.com/derjasper/Scanner)
• taking a photo and process it
• image rotation and filter selection
• simple UI
• started implementation of edge preview using QVideoFilter

• get it to work with the new container-based Ubuntu SDK (and link open-cv statically or include it in the click package)
  • Qt 5.5 is needed for QVideoFilter, which is not available in the container, so you may set up a desktop kit for development
• content hub integration
• live preview of edges
  • convert a QVideoFrame to a cv::Mat
  • run edge detection in own thread
• improve filters and/or make them more customizable
