Darwin Wallet enables blind and visually impaired users to quickly recognize paper money. It uses the phone's camera to detect currency denominations for U.S., U.K., Canadian, European Union, and Australian bills. Simply hold the bill in front of the phone's camera, and the app will speak its value. The app uses the phone's camera and OpenCV (via Android NDK) to analyze and identify the currency image.
