Mobile Currency Reader


This mobile currency reader project intends to make tasks such as recognizing the values of different dollar bills easier for blind and visually impaired people.


Team 1 – The mobile currency reader will accept an image as an input and attempt to match it against reference images. This is currently done from the command line.

Team 2 – The application will first prompt users to capture an image of the holding bill, and the captured image will be transferred to the server. Then the server will process the image in order to recognize the value of the bill. Once the value of the bill is determined, the server will select the appropriate audio file to play to the users.

Current Issues

The current implementation is very buggy, and needs work. It only correctly identifies in specific cases, and some cases can cause exceptions.

Future Plans

From the prototype developed at SS12, we want to develop a more robust identification algorithm and implement it on the Google Android platform.
