Vision is an educational-grade application, although fully functional. It demonstrates face recognition functionality using OpenCV integration. The application uses training to extract features from photos and then recognition of an unknown photo against the training dataset.

The app uses android.permission.CAMERA, which is used to the enable acquisition of photos using the phone's camera. It also uses android.permission.WRITE_EXTERNAL_STORAGE to facilitate saving photos to the external storage available to the mobile phone. No user or any other sensitive data are being shared, or by any means being transferred to a third party by the developer of this app. All photos are being stored in the user's mobile phone and are not being transmitted to any other location.
