RoloScan
RoloScan is a multi-purpose tool to turn text from photos and images into selectable, editable text. You can take a picture of text or put an image file on your phone. RoloScan will use the Tensor Flow Artificial Intelligence toolkit for computer vision to open that image and read the text in it.
Unlike previous apps, RoloScan is an open-source project easily found on GitHub. It is available for sale on the Google Play Store so that people who do not know how to build and side load apps can get the opportunity to use the tool
It is also part of an Android Code to teach advanced Android coding techniques:
the intent system
the new TensorFlow Computer Vision APIs
the ContactsContract content provider, via Intent
